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

* 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

Package s2 is a library for working with geometry in S² (spherical geometry).
Its related packages, parallel to this one, are s1 (operates on S¹), r1 (operates on ℝ¹),
r2 (operates on ℝ²) and r3 (operates on ℝ³).
This package provides types and functions for the S2 cell hierarchy and coordinate systems.
The S2 cell hierarchy is a hierarchical decomposition of the surface of a unit sphere (S²)
into ``cells''; it is highly efficient, scales from continental size to under 1 cm²
and preserves spatial locality (nearby cells have close IDs).
More information including an in-depth introduction to S2 can be found on the
S2 website https://s2geometry.io/
