In pygeos, we have a general apply method to apply a function on the coordinates and recreate geometries from those transformed geometries (we probably need to rename it to transform, but that's another issue).

This speeds up the affine transforms again a bit (which saw a slowdown in #983). The specific example of #983 (comment) is now again at the same speed as with released Shapely:

In [1]: from shapely.geometry import Polygon

In [2]: poly = Polygon([(0,1), (1, 2), (2, 1), (1, 0), (0, 1)])

In [3]: %timeit poly.minimum_rotated_rectangle
275 µs ± 6.98 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

Now, for single geometries, I don't think we need to expect speed-ups, certainly not compared to the cython code (that I removed here).
