[Feature Request] Add support for package denylist

[frrad]

Thank you so much for adding the * feature from https://github.com/beartype/pytest-beartype/issues/6 so quickly!!!

It works great! Perhaps predictably though, some of my packages don't pass. I'd like to be able to do "everything, except for x, y, z" so that I can fix the broken ones gradually while still opting in new packages automatically.

...heh. This intersects exactly with @beartype feature request beartype/beartype#407. Unfortunately, it looks like this is a tag-team effort, @tusharsadhwani. Specifically:

• On the @beartype side, I'll need to actually implement beartype/beartype#407 by supporting a new BeartypeConf.claw_skip_package_names configuration option. My eyes are watering with exhaustion. :face_holding_back_tears:
• On the pytest-beartype side, I'll then beg you to expose a similar command-line configuration option (e.g., --skip-package-names='awful_package, horrible_module').

Sadly, I'm the hold-up here. Multiple users are now beseeching the heavens for this. So, this will definitely happen. But... I'm just sooo slow. I promise to do this as soon as feasible. But... it's best not to trust my promises. Therefore, I also promise to immediately merge any PR implementing beartype/beartype#407.

If anyone's interested in a PR, let me know and I'd be just delighted to guide your capable keyboard fingers. :smile:

Resolved by e6bf380. Thanks a heap overflow to intrepid QA guru @tusharsadhwani for the recent resolution at PR #9! Problematic packages may now be ignored by passing a package blacklist (ban list, deny list) as the new --beartype-skip-packages option: e.g.,

--beartype-skip-packages='bad_package,good_package.awful_submodule'
