@sxjscience this removes with_seed() from existing function. Should have been caught...

Oops, you are right, could you make a PR to fix it?

Fast pseudo-2D transpose kernel.
Supports only transposes that satisfy:
Exists n and m such that:
params = (0, ..., n-1, n+m, ..., params.size, n, ..., n+m-1)
Example: (0, 2, 3, 1) or (0, 3, 1, 2), but not (0, 2, 1, 3).
