Automatically convert pre-0.95 annotations to use Annotated

[DJRHails]

Annotated is objectively a better solution all round, but I've always struggled to adopt it because of the pain to rewrite existing codebases.

Recently I've been experimenting with bulk refactoring using libCST, and I've implemented a converter.

Should be easy to use, just pip install pymender + pymender FastAPIAnnotated ..
