Python 3.9 support

[gitpushdashf]

Currently, google-fhir requires Python 3.7 or 3.8. With 3.9 out in production, what would it take to support it?

Thank you!

IIRC there may be some minor changes that need to happen with primitive time utils to support 3.9, but that's all that sticks out in my mind. I would like to land a couple minor improvements to the infra around testing pypi artifacts, but then would be happy to take a look at getting this in!

[gitpushdashf]

That sounds good, thank you!

[gitpushdashf]

Hey! Do you have any update on this by chance?

[Cam2337]

I went ahead and made the minor modifications to support Python 3.9, and added some additional support in build_distribution.sh to test against all supported major/minor versions prior to staging the release artifacts. These changes are now in review. Apologies for the delay!

[gitpushdashf]

Fantastic! Thank you so much!

Replicating a queue of changes -- note that the support for this is in the repository, but will not be visible to pip/pypi users until we cut a new package. Am going to try and target tomorrow or the next day to do this.

Awesome! We're very much looking forward to it.
