PERF: use dask.bag in Tessellation

[martinfleis]

Fixes #295

@matthew-law You were right, in my test, the single-core implementation was actually a bit faster than parallel. This seems to fix the problem.

I am a bit worried though. I used bag initially and then when moving the code to momepy, I have switched to dask.Series. I just don't remember why. Can you try this version on your data? My assumption is that it should go from 30 minutes to about 5.
