Load ignore rules from a lines separated file

[Urik]

Feature request description

Would be very nice being able to load ignore rules from a lines separated file in addition to the "--ignores" flag.
This would make it possible to source control the ignores rules, and simplify CI pipelines.

Any extra info

Already have a PR for this feature:
