Expose symphonia feature of rodio for bevy_audio

[harudagondi]

What problem does this solve or what need does it fill?

Related to #6299, bevy_audio is limited to wav, ogg, flac, or mp3 audio formats. However, rodio have the symphonia feature which enables file formats and codecs such as:

• ISO/MP4
• MKV/WebM
• OGG
• Wave
• AAC-LC
• ALAC
• FLAC
• MP3
• PCM
• Vorbis

What solution would you like?

Add a new feature in bevy_audio and possibly in bevy as well that enables this feature

What alternative(s) have you considered?

Implement your own Decodable type that uses the Decoder from rodio that has the symphonia feature enabled. (I don't think this works)

Additional context

#3145 is a tangentially related issue that discusses the viability of symphonia as a "backend". (symphonia is a decoder and a demuxing framework, not an audio backend)

Fully on board. Should be a simple PR. For enabling audio formats, probably follow what was done for the various image and asset formats?

Please keep said feature optional or at most conditional on other features. To take a page out of Unity and Unreal's books, their built games only support a small list of codecs and containers at runtime, but support transcoding many more in the editor on asset import. This avoids needing to ship the equivalent of ffmpeg with every game download.

Yeah I'm just asking for a Cargo feature reexport to symphonia-all of rodio. Should be simple to do.

For an example see #5857, where I reexported the mint feature of glam in bevy_math.

Hi. Is anyone working on this? Can I help on this?

[harudagondi]

As far as I am aware, no one is working on this right now. =)

If you're interested in helping, you should check out rodio's features first.

Hi, I've went through the rodio's features and they have separate features for different audio formats. I think it's better to have control of what audio formats to support instead of symphonia-all. Thus, I make it separate like rodio.
