Consider switching from toml to tomli

[sobolevn]

toml was last released on 02.11.2020: https://pypi.org/project/toml/#history
There are multiple known bugs: https://github.com/uiri/toml/issues

Maintainer is not supporting their project: uiri/toml#361

Multiple big projects like mypy, black, typeshed have already switched.

The transition seems to be rather simple: basically swap import toml with import tomli and use a proper encoding when calling loads.

If this is something you think should be done, I can send a PR.

PEP 680 has been accepted and will be in Python 3.11 🎉

I think it would be a good idea to switch from from toml to tomli, it will make it easier to switch to the stdlib tomllib at some point in the future.

Sorry @sobolevn, I didn't notice the last sentence of your post. Not sure if you were already working on this, but I have created a PR which fixes this in #67.
