Write a real port

[mccoyst]

This would be good for three reasons:

• Remove the cgo requirement
• Improve performance significantly, since the decoded data won't have to be copied from C land.
• Understand it well enough to write a generalized function that takes a Reader.

Hello, any progress about the real port?

[mccoyst]

It's in stasis — I've been very busy with work and lots of other life events, so all of my side projects have taken a hit. I'm actually hoping to pick it back up sometime this summer. 😁

I would love to see this. https://github.com/tcolgate/mp3 is a native MP3 decoder if that's helpful to anyone instead.
