Support play PCM16L from disk

[Laky-64]

Regarding my previous question:
pion/mediadevices#339

It's possible also to add possibility to play PCM16L audio file from disk?

Thank you in advance

Sorry this didn't get addressed sooner!

No Pure Go Opus encoder exists today. If someone is building today your best option for this is use GStreamer or FFmpeg I have linked examples.

If you are ok with lower quality you can do alaw/mulaw and use something like github.com/zaf/g711.

Someday I hope pion/opus has a full encoder. It is very unlikely to happen soon though. If someone reading this is inspired to make Go and media better I would love your help though :)
