Jaxtyping v0.2.0

This version of jaxtyping is a backwards-incompatible change to the syntax. The good news is that we now support static type checking, have no more ambiguous variable names, and can support annotating non-JAX-arrays!

See #16 for how to upgrade, and #13 for the discussion surrounding this.

Full Changelog: v0.1.0...v0.2.0
