Propagation submodule refactored

Jens Luchtrequested to merge
refactor-propagators into master

FresnelPropagation becomes (more correctly phrased) FresnelTFPropagator.

New features

  • NumPy arrays directly supported. No need to cast to PyTorch tensors anymore.
  • (Zero) padding, with adjustable padding factor by npad=2
  • simulate_hologram simple-to-use function
  • Scalar (single) distance propagation. No need for auxiliary axes.
  • correct data type handling.

Closes #32 (closed).
