ENH: add orientation and shared_walls functional versions

[martinfleis]

Orientation:

    # buildings
    # old: 3.23 s ± 77 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
    # new: 932 ms ± 12.5 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
    # streets
    # old: 374 ms ± 5.56 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
    # new: 62 ms ± 681 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

Shared walls:

    # 8.68 s ± 28.7 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
    # 10.3 s ± 17.2 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

This is slower but it does not cause erroneous results coming from overlapping polygons.

LGTM. One small typo.
