Add sources generated with McStas notebook for all 16 instruments.
The new default ess source is created as the average of all sources.

The high-resolution binning will then enable us to use uniform noise during the sample instead of gaussian noise, which would fix issues in sampling optimization in #136

We also add the notebook that was used to generate the sources. It is not ran as part of the docs, as it is too expensive to run in CI.

Updated default ESS source profile:
