Closes #103

@marcosschroh Thoughts? I think the typing.Annotated approach makes a lot more sense than the other PR as all we are aiming to use the native type but communicate additional information to the package to Avro serialization + schema generation. Which is exactly what it's for.

Are you also happy with this testing?

Looks much cooler than my approach, thank you!

BTW, you can automate closing related issues by proper pull request description.

I think @marcosschroh will ask for documentation update

There is a bit of docs in here. Wasn't really sure what else to add!
