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