[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
