BUG: Fix name of force2D when generating angles (GLRLM and GLSZM)

Because GLRLM and GLSZM are forced with distance 1, other parameters are passed manually to the generate angles function. However, the `force2D` parameter was named incorrectly and as such, ignored. Fix the name to enable forced 2D extraction for GLRLM and GLSZM.

+- For GLRLM and GLSZM, force2D keyword is passed manually, but was incorrectly named and therefore ignored. Fix name to
