MAINT: minor performance improvement

Merge two loops and move invariant of switch case out of inner loop.
Improves performance by 5% - 10% depending on the order.
MAINT: tell compiler that edge interpolation is less likely

This should be true for most cases where performance is relevant.
Improves performance by about 5% on images > (500, 500) with order three.
MAINT: add map_coordinate tests with non-continous arrays
ENH: unstable beginning of expm_action implementation
ENH: matrix power operator
ENH: expm_action implemented and tested
MAINT: move the main function to the beginning of the module
BUG: mired in scipy/numpy ndarray/matrix/sparse hell
MAINT: final commit before ripping out the buggy attempts to support sparse matrices
ENH: expm_action for sparse matrices added and tested
