Specify Permutation Index for PartialPivLU and FullPivLU
Reference issue
Fixes #2475 (closed) Fixes #2592 (closed)
What does this implement/fix?
Provides a mechanism to specify the permutation index type for LU decomposition classes. This is primarily useful for Lapacke ILP64 interfaces that require a 64 bit integer type for the permutation. Following this patch, all the implemented lapacke wrappers should be compatible with ILP64.
