rip-py: Split things and support Blu-ray

Browse Source 
We're using a `libbluray2` wrapper by the same person that also built
`pydvdread`. At the same time, we dump supporting to parse `mpv` output,
because that was too unreliable anyways and keeping it just means more
maintenance overhead.

To provide a better overview, we've split up the DVD and Blu-ray
functionality into own modules
