CL Interface Step 3: Create pipeline stage to compute and save stacked Cluster Shear Profiles

[cavestruz]

We want TXPipe to construct stacked cluster profiles corresponding to a given richness and redshift bin.

Open Question: Stack the constructed profiles from Step 2 or all the background galaxies from Step 2?

Goals:

• Create a pipeline stage to construct stacked profiles
• Use the cluster bin definition from another piepline stage
• Save a SACC file with meta data (e.g. richness, redshift bins, clusters in the stack, etc.)

After discussion, this will be done in Step 2 #307 .
