Version 2.0.0 — The first REAL version

Significant breaking changes in this version, but these were essential. Most users of this library shouldn't have to make many changes as few users were using the library for audio reading and writing, where the changes are.

• Also @irh has cleaned up much of the source code so it all passes clippy.
