ENH: add Streetscape class

[martinfleis]

This adds code implemented by Alessandro Araldi and his team, wrapped into a user friendly API that can be accessed from momepy. It essentially enables analysis of streetscape outlined in 10.1111/gean.12416.

The code is sloooooooooooooooooooooooo... ah... oooooooooooooooow. But it runs. Anyone is happy to refactor. I have picked some low hanging fruits but it is in a dire need of complete refactoring for which I do not have a capacity. It should follow the logic we have in street_profile and its performance but is now several orders of magnitude slower. But hey, it works and allows reproducible research. so yay!

One thing to note - I have added plots from cadastre and DTM from Prague's data portal to the bubenec.gpkg.
