@jonasteuwen This is ready for merge.
Some updates:

• I fixed pylint with py 3.10 (required a small import from skimage change)
• For some reason it threw an issue for cnp.int_t in cython which I replaced witg cnp.int64_t
• For docker, it needs more work and will do a seperate PR

LGTM. Nice work!
