Add the capability to ignore patter of files

[agirorn]

For example, when running yardman on a python project that constantly is updating the pycache folder it would be nice to be able to add and ignore of excluding patter

yardman tests --ignore tests/__pycache__ "clear && pytest -vv tests"

yardman tests --ignore-pattern '*__pycache__*' "clear && pytest -vv tests"

Then also include a convenience argument

yardman tests --ignore-python "clear && pytest -vv tests"
