AJM decode PoC

[ga2mer]

This PR is marked as draft as it is still in development and is not recommended to be pushed into the main branch

What works:

• Simple At9 decoding
• Simple MP3 decoding
• Simple ADTS AAC decoding
• Simple Audiodec

What doesn't work:

• ring buffer jobs
• it's not async, so it blocks the thread while decoding
• doesn't work properly

What needs to be done:

• multiple frames jobs with ring buffers
• gapless decoding
• resampling
• reset contect
• extend codec
• switch codec
• correct working logic
• few small things
• refactoring, right now the code is unbelievably awful and contains a lot of hacks and debugging logs

Mostly untested in games

Once this works well in synchronous, it will need to make an asynchronous task queue, since on the original platform, AJM works with a separate hardware and it works without blocking the main hardware threads (at least until you ask for it)
