Comparison with deptry

I am currently using https://github.com/fpgmaas/deptry

It seems to have similar objectives to this project; perhaps it could be good to document the relative strengths of each package for different tasks.

Hi @nathanjmcdougall . I welcome a PR from anyone who is familiar with the details. I think for new projects, deptry is best (at least for now!) as it is more actively maintained and it is faster and it does not rely on internals of pip which may change.
