Redo av codec settings & selections to accomodate webm

Browse Source 
Allows for ranked preferences for h264, av1, and vp9 codecs in
settings, along with equal preferences which are tiebroken using
smaller file size.

For each quality, gives av-merge a list of video sources
and audio sources sorted based on preference & file size. It
will pick the first one that the browser supports.

Closes #84
