Add Mauve metric
MEMBER
Hi ! The CI was failing because `mauve-text` wasn't installed. I added it to the CI setup :)

I also did some minor changes to the script itself, especially to remove `**kwargs` and explicitly mentioned all the supported arguments (this way if someone does a typo with some parameters they get an error)
