Pyproject py versions

Summary

The summary should expand on the title of the pull request. What is the expected effect of the
pull request? Specifically, indicate how the behavior will be different than before the pull
request.

Tests for 3.9, 3.10 and 3.11. It'd be great to add tests against 3.12 but it doesn't look like travis supports 3.12 yet. Also adds a basic pyproject.toml to support PEP 517 builds.

Bug Fixes/New Features

• Tests on multiple python versions
• PEP 517 support
