Description

This PR introduces an initial Python implementation of SSP2.

Known limitations

  • Periodic boundary conditions: Not yet supported. Further discussion is needed regarding endpoint handling.
  • JAX pinned to 0.7.2: Newer versions throw the following error when combining FFT-based filtering with interpax interpolation:
  RET_CHECK failure (external/xla/xla/backends/cpu/runtime/fft_thunk.cc:167)

Example and test: Currently copied from the SSP1 counterparts with just the projection method switched.
