v2.0.0

Stable! Finally! After 4 years in development! Many changes have made it in since rc.3, including (unfortunately) some last minute breaking changes. But documentation has been cleaned up to a point where we finally feel comfortable committing to things as they are.

If you haven't been following along with the 2.0 changes here is a brief overview

• Completely rewritten API decoupled from serde
• no_std support
• Official format specification
• Default configuration changes
• Increase MSRV to 1.85.0
