Thermalized LB: test 4 rel time model velocity and pressure fluctuations

Merged RudolfWeeber requested to merge RudolfWeeber/lbmpy:fluctuation_test into master

This changes the fluctuating LB test to match as closely as possible what we are going to use. Model with 4 relaxation times for shear/bulk/odd/even modes. Tests:

  • mass conservation
  • momentum conservation
  • <m v^2> = k_B T
  • Maxwell velocity distribution
  • average stress tensor
  • stress tensor fluctuations accodring to Duenweg, Schiller, Ladd
