Issue 309 cl data vector

This PR is dedicated to put together the different part of the Cluster pipeline.

Trying to work on feeding cluster ensemble with cluster tomography :

[marina-ricci]

This is what I obtain for the ensemble profile on the 20deg2 :

The error bars are from the sample covariance.

[marina-ricci]

This is the stacked profiles in bin of redshift/richness for 20deg2. There is a clear problem with the profile, but the pipeline is running !

[marina-ricci]

There is also a problem to fix maybe on the CLMM side : when there is no background galaxy in a radial bin we want to fill the profile with None to preserve the size of the profile otherwise we can't stack.

[marina-ricci]

What was done :
we now have preliminary pipeline to compute stacked delta_sigma profiles for each richness/redshift bins. This works on the 20deg2 extracted from cosmoDC2.
Problems, limitations and to-dos so far :

• The cluster_esemble stage output pickle files. All Cluster related stage are not parallelized. This may not scale.
• There is a clear problem with a profiles that are wrong. I suspect a problem in the cluster_shear stage. We need to investigate.
• There is a problem with the radius : if a given cluster does not have background source in a given radial bin, this prevent the stack to be compute. This likely has to be changed in CLMM directly.
• We miss the last stage to read outputs and only save needed information in SACC format.

In CLMM, make_radial_profile has a keyword include_empty_bins that is False by default. Turning it to True when calling that function in TXPipe (here) should solve the problem (I think).

[marina-ricci]

Ah great! I'll update that then (Or anyone before me)

@marina-ricci - I started completing the CLClusterShearCatalogs demo notebook, in the spirit of what you did for the counts one. Not finished and still needs work though.
