Haloes module into main and pip version

[sibirrer]

Description

The halos module is only accessible in a specific branch. We are developing a strong lensing simulation pipeline for LSST (and beyond), currently mostly developed in the gg_lensing branch: https://github.com/LSST-strong-lensing/sim-pipeline/tree/gg-lensing
We (meaning @trivialTZ) are now also trying to implement a halo rendering for line-of-sight structure (and potentially even more), using the SkyPy halo module as well as effectively the tools in SkyPy used for galaxies but now to render a light cone for haloes.
The pull request using and implementing these additional features is presented here
sibirrer/slsim#7

It's hard to develop another package while linking to a specific branch of SkyPy. I would like to see the halo module merged to main and made a release version.
We are also happy to put some of these halo rendering parts into the SkyPy halo module in the intermediate and long term.

Thank you very much!

Hi @sibirrer ! Yes, we have been intending to merge the halos and power spectrum modules as the next task for SkyPy v0.6, we have just been in a dormancy period because of other time commitments. We should get on with this now though!
