Unoriented Stacks Updates

Back when I had first made unoriented stacks on clusters in the ACT y map and on the Websky y map, the two profiles had been quite different. I fixed a few things:

1) The smoothing scale was slightly different between the two (I had a factor off in the FWHM to sigma conversion of the Gaussian beam) 2) The mass bins did not match well. I was matching by number and taking the top most massive Peak Patch halos to match the number of Redmapper clusters. I think this was including more massive PkP halos. Now I am binning clusters in richness and matching the bins for halos in the sims by using the richness-to-halo mass relation from weak lensing done for Redmapper by McClintock et al. 2018. 3) The Websky map was not filtered to match the ACT y map. I now have filtered modes of ell < 80 like Mat had done to the ACT y map.
