--ignore not considering dir name (and probably broken in other ways) #8

it seems that --ignore doesn't take in consideration the full path of the file, so it's impossible to exclude a sub-directory. So it's not really a "glob/.gitignore match" as documented, as they work on the whole path.

$ dirhash -l ./ --ignore .venv | grep '\.venv' | head -1
.venv/bin/activate

It also seems that it breaks other ignores: .pyc can be excluded:

$ dirhash -l ./ --ignore \*.pyc| grep '\.pyc$' | head -1

but using two excludes pattern they come back.

$ dirhash -l ./ --ignore \*.pyc --ignore .venv | grep '\.pyc$' | head -1
.venv/lib/python3.7/__pycache__/__future__.cpython-37.pyc

dirhash version is 0.2.1
