Supported audio formats are not listed in code or docs

[Anthonyntilelli]

I'm working on converting a sounddevice frame into an av.audio frame, and as part of this process, I need to specify the audio format string. However, the documentation AudioFormat docs does not list the supported format strings, nor does there appear to be a way to programmatically enumerate them.

It would be very helpful to have a documented list of supported audio formats, and ideally, a method such as av.audio.format.AudioFormat.all_formats() to retrieve them programmatically.

This limitation also seems to apply to video formats—there is no clear way to list supported pixel formats either.

Request:

Please document all supported audio and video format strings.
Consider adding a public API to enumerate supported formats programmatically.
