pre-commit hook

[KPilnacek]

Is your feature request related to a problem? Please describe.
I'd like to easily use bandit with pre-commit

Describe the solution you'd like
Add a .pre-commit-hooks.yaml (need not to be touched after creation)

Describe alternatives you've considered
I already created a mirrors repository in my profile which just mirrors the bandit repo. However, there are two problems with that:

• new versions of bandit need to added manually (can be solved by people from pre-commit
• missing official support from bandit

Additional context
Other packages (black, prettier, talisman, etc.) do have direct support of pre-commit as well.
