Documentation Is Badly Out Of Date

[mechanyx]

I was bitten by the issue in #287. From that issue I see that the documentation has been updated but the Documentation link on the project's main page points to https://capnproto.github.io/pycapnp where the 1.0.0 documentation is available. 1.0.0 was 9 releases ago from November of 2020. I do not see the newer documentation online anywhere. Incorrect docs are a major hurdle to adoption of your package as incorrect docs are worse than no docs. I would strongly suggest updating the online documentation.
