This adds a longer description of the resolution parameter and corrects
some of the wording of the docs.

Different versions of python/numpy/scipy will produce slightly different results

For muon Nexus v1 files, there is always a one-to-one mapping between
spectrum number and detector ID.

Set detector IDs in workspace so that they are correct in the case that
not all spectra are loaded, e.g. load spectra 1-5, 8-10 then detector IDs
shouldn't be 1-8 but 1-5, 8-10 also.

Add a note to documentation.

This is done at the request of the Corelli instrument scientists to be better inline with what the users expect the algorithm to do. This simply changes the scale of the weight by a factor of the duty cycle (c≈0.498).

The documentation has also been updated which resolves #11381
