Seeding numba functions

[petergaemers]

There are a few numba'd functions which use random numbers like luminescene timings and the add_noise.
When setting a seed for the random number generator this is NOT applied to the numba'd random generator

So we need to fix this. This shouldn't be hard, something like pass the seed as a argument to the relevant functions. But make sure to only seed once

Something like this:
