Feature: Add passing pyglet encoders and/or automatic Ogg support

[pushfoo]

Enhancement request:

TL;DR: @DigiDuncan pointed out we can't really load .ogg through arcade

What should be added/changed?

1. Add a way to pass a decoder supported by pyglet's media.load function
2. (Optional / risky) Smart and helpful pyogg / PyOggDecoder warnings

What would passing in a decoder would it help with?

Improve arcade user experience by allowing sound loading to:

1. take specific decoders such as pyglet's PyOggDecoder
2. avoid subclassing Sound as in Charm's current code
3. without having to file tickets for new formats (example: QOA)

Changes needed:

1. Add a decoder keyword argument to arcade.sound.Sound.__init__
2. ~~Add a temp Decoder protocol to annotate it before upstreaming matching pyglet's codecs~~ Use the existing MediaDecoder type
3. Document the change
4. Update the sound page in the programming guide

Follow-up Work

1. Add an example
2. Make upstream pyglet PRs to help with https://github.com/pyglet/pyglet/issues/1084:
   1. ~~Define a Decoder Protocol type matching pyglet's pyglet's codecs~~
   2. Add argument and return annotations to the codecs

Thanks for writeup, pushfoo! +1.

Follow-up from earlier reading tonight:

1. There's already a MediaDecoder base type in pyglet
2. Although we could define a MediaDecoderLike protocol, it may be redundant for now
