PCM_S16LE codec ID commented out

[xd009642]

So the PR to add the unknown codec ID #156 while good for avoiding unnecessary panics wouldn't have occurred to me if PCM_S16LE wasn't commented out in the codec ID enum. I'm just wondering why this was done and if the comment can be removed somehow as it's a pretty common codec and I can't think of an ffmpeg version that doesn't include it

Tracked it back to 4f270f98fbc where the commit message just says "Chore: make stuff build again"
