Function build_permute_plan 

pub fn build_permute_plan(
    dims: &[usize],
    src_strides: &[isize],
    dst_strides: &[isize],
    elem_size: usize,
) -> PermutePlan

Build a permutation plan using bilateral fusion and HPTT-style blocking.

This is the main entry point. The returned plan is consumed by execute_permute_blocked.
