Depend on tomli rather than toml

[johnthagen]

• load config from pyproject.toml or setup.cfg #79

added TOML parsing support.

It added a dependency on the toml package:

autoflake/setup.cfg

Line 25 in 9fd81fb

toml>=0.10.2

Since that PR was originally opened, the community has mostly moved from toml (which has historically not been maintained well) to tomli. tomli was added to the Python standard library in Python 3.11.

One primary benefit of using tomli is that eventually the dependency can be dropped all together when Python 3.11 is the oldest supported Python version. It also reduces install time as most other packages in the ecosystem are using tomli.
