Speed up code
When multiple wavelength ALMA data is fitted, then the per model computation time is large. Find out which modelling steps are the most time consuming and optimize as much as possible.
Possible optimization:
- do not compute and store synthetic visibility when not needed
- try ifast = 1, 2 in the thermal Monte Carlo of RADMC-3D
- compute synthetic images at all wavelength simultaneously (possible if scattering is off)
- print timing information on request
