Uniform crop only in horizontal direction

[JortJacobs]

Would it be possible to have uniform crop only in horizontal direction?
Or more general, specify for each direction whether it should be uniform across pages?
E.g.

u4 LEFT BOTTOM RIGHT TOP
u4 false true false true

The --uniform4 (-u4) option is implemented for the next version. The usage is, e.g., -u4 f t f t. The --samePageSize4 (-s4) option is similarly implemented to go with it.

The new version has been pushed to PyPI as 2.1.4.
