Changed build system to maturin to add rust extensions

This meant moving the python source out of src/ . I dislike this project
structure but will do for now while I think of something better.
setup.cfg is no longer needed and all options are either in pyproject.toml
or Cargo.toml. I still need to figure out a lot of stuff.
