[feature] more filetype support! (#3107)

Browse source 
* add more supported file types to our media processor that ffmpeg supports, update supported mime type lists

* add code comments to the supported mime types slice

* don't check for zero value string, just parse

* remove some unneeded consts which make the code a bit harder to read

* fix test expected instance media mime types, use compact ffprobe json, simple media processing by type

* final tweaks to media processing code

* don't use safe divide where we don't need to
