REF: reimplement mrr on top of shapely

[martinfleis]

Resolves the issue seen in https://github.com/pysal/libpysal/issues/681 where opencv causes installation headache. Since we already depend on shapely, there's no need to depend on OpenCV, so using shapely's minimum_rotated_rectangle, computing the angle manually and coercing the resulting array into the opencv-like order (which is the opposite compared to shapely).
