Investigate supporting older versions of Python #90
Description
Is your feature request related to a problem? Please describe.
Some project platforms aren't on the latest-and-greatest Python versions. It might be worth adding some new versions to the matrix and seeing what works. Should probably stop on or after 3.6 as that version just hit EOL. Currently it is locked on 3.9 in PyPI, meaning that pip can't even find that package if you are on an older version.
Describe the solution you'd like
- Tests should pass on older versions of Python.
- Documentation should be more specific on which versions are supoprted.
- Package metadata should match the findings above.
Additional context
Currently working on a project, and stuck on 3.6 as that is the latest package that the OS packaging tool maintainers have released.
