Subject: [PATCH] Use sys.version_info in compatibility layer (#220)

* Use sys.version_info in compatibility layer

Fixes #219

Static type checkers are able to understand checks against sys.version_info much better than try-except. In general, if type checkers tried to handle conditional imports fancily, this would result in unsoundness.

Another reason is that you may have tomli conditionally installed based on Python version, in which case a type checker would not even have a way of knowing what tomli is.

* [pre-commit.ci] auto fixes from pre-commit.com hooks
