Added `geometry.Line` base

This pull request adds the Line class to the pygame.geometry module.

It also adds the xa, ya, xb, yb, a, b attributes, str functionality (for printing), and the copy method. It also adds their associated docs and tests.

Important Note As things stand, we don't accept building a Line with the exact same start and end point. This isn't strictly necessary as we reversed this same behaviour with the Circle class. Just tell me if this should be changed in this PR on a following one.

Is there any specific reason why the coordinates are named with xa, yb instead of ax, by? The current is annoying for me to parse mentally, as it looks backwards and the 'subscript' appears in front of the point.
