Be able to configure the allowed prefixes list #672

Description

#414 and #551 introduced what is a breaking change for my team, since we want cz check to fail in the CI, in case of a fixup.
This comment suggests to add this list to the config, which IMO is a good idea.

Possible Solution

I've already written the PR to implement this new config / cli argument here, but, as written in contributing.md, I'm creating an issue to validate this change first.
