[feature] support processing of (many) more media types (#3090)

Browse Source 
* initial work replacing our media decoding / encoding pipeline with ffprobe + ffmpeg

* specify the video codec to use when generating static image from emoji

* update go-storage library (fixes incompatibility after updating go-iotools)

* maintain image aspect ratio when generating a thumbnail for it

* update readme to show go-ffmpreg

* fix a bunch of media tests, move filesize checking to callers of media manager for more flexibility

* remove extra debug from error message

* fix up incorrect function signatures

* update PutFile to just use regular file copy, as changes are file is on separate partition

* fix remaining tests, remove some unneeded tests now we're working with ffmpeg/ffprobe

* update more tests, add more code comments

* add utilities to generate processed emoji / media outputs

* fix remaining tests

* add test for opus media file, add license header to utility cmds

* limit the number of concurrently available ffmpeg / ffprobe instances

* reduce number of instances

* further reduce number of instances

* fix envparsing test with configuration variables

* update docs and configuration with new media-{local,remote}-max-size variables

// Shape represents polygonal geometry in a flexible way. It is organized as a
// collection of edges that optionally defines an interior. All geometry
// represented by a given Shape must have the same dimension, which means that
// an Shape can represent either a set of points, a set of polylines, or a set
// of polygons.
//
// Shape is defined as an interface in order to give clients control over the
// underlying data representation. Sometimes an Shape does not have any data of
// its own, but instead wraps some other type.
//
// Shape operations are typically defined on a ShapeIndex rather than
// individual shapes. An ShapeIndex is simply a collection of Shapes,
// possibly of different dimensions (e.g. 10 points and 3 polygons), organized
// into a data structure for efficient edge access.
//
// The edges of a Shape are indexed by a contiguous range of edge IDs
// starting at 0. The edges are further subdivided into chains, where each
// chain consists of a sequence of edges connected end-to-end (a polyline).
// For example, a Shape representing two polylines AB and CDE would have
// three edges (AB, CD, DE) grouped into two chains: (AB) and (CD, DE).
// Similarly, an Shape representing 5 points would have 5 chains consisting
// of one edge each.
//
// Shape has methods that allow edges to be accessed either using the global
// numbering (edge ID) or within a particular chain. The global numbering is
// sufficient for most purposes, but the chain representation is useful for
// certain algorithms such as intersection (see BooleanOperation).

// NumEdges returns the number of edges in this shape.
NumEdges() int
// Edge returns the edge for the given edge index.
Edge(i int) Edge
// ReferencePoint returns an arbitrary reference point for the shape. (The
// containment boolean value must be false for shapes that do not have an interior.)
//
// This reference point may then be used to compute the containment of other
// points by counting edge crossings.
ReferencePoint() ReferencePoint
// NumChains reports the number of contiguous edge chains in the shape.
// For example, a shape whose edges are [AB, BC, CD, AE, EF] would consist
// of two chains (AB,BC,CD and AE,EF). Every chain is assigned a chain Id
// numbered sequentially starting from zero.
//
// Note that it is always acceptable to implement this method by returning
// NumEdges, i.e. every chain consists of a single edge, but this may
// reduce the efficiency of some algorithms.
NumChains() int
// Chain returns the range of edge IDs corresponding to the given edge chain.
// Edge chains must form contiguous, non-overlapping ranges that cover
// the entire range of edge IDs. This is spelled out more formally below:
//
// 0 <= i < NumChains()
// Chain(i).length > 0, for all i
// Chain(0).start == 0
// Chain(i).start + Chain(i).length == Chain(i+1).start, for i < NumChains()-1
// Chain(i).start + Chain(i).length == NumEdges(), for i == NumChains()-1
Chain(chainID int) Chain
// ChainEdgeReturns the edge at offset "offset" within edge chain "chainID".
// Equivalent to "shape.Edge(shape.Chain(chainID).start + offset)"
// but more efficient.
ChainEdge(chainID, offset int) Edge
// ChainPosition finds the chain containing the given edge, and returns the
// position of that edge as a ChainPosition(chainID, offset) pair.
//
// shape.Chain(pos.chainID).start + pos.offset == edgeID
// shape.Chain(pos.chainID+1).start > edgeID
//
// where pos == shape.ChainPosition(edgeID).
ChainPosition(edgeID int) ChainPosition
// Dimension returns the dimension of the geometry represented by this shape,
// either 0, 1 or 2 for point, polyline and polygon geometry respectively.
//
// 0 - Point geometry. Each point is represented as a degenerate edge.
//
// 1 - Polyline geometry. Polyline edges may be degenerate. A shape may
// represent any number of polylines. Polylines edges may intersect.
//
// 2 - Polygon geometry. Edges should be oriented such that the polygon
// interior is always on the left. In theory the edges may be returned
// in any order, but typically the edges are organized as a collection
// of edge chains where each chain represents one polygon loop.
// Polygons may have degeneracies (e.g., degenerate edges or sibling
// pairs consisting of an edge and its corresponding reversed edge).
// A polygon loop may also be full (containing all points on the
// sphere); by convention this is represented as a chain with no edges.
// (See laxPolygon for details.)
//
// This method allows degenerate geometry of different dimensions
// to be distinguished, e.g. it allows a point to be distinguished from a
// polyline or polygon that has been simplified to a single point.
