This adds a new template that regresses components of detector data that are correlated with a shared data field whose values are periodic (HWP angle, Azimuth, etc). The values of the periodic field are binned and a different set of template amplitudes are solved for each detector and each observation. Additional changes: * Unit test for fake HWPSS removal in satellite and ground simulations. * Unit test helper for healpix map plotting, similar to the helper function for WCS plotting. * Added functions to the Offset template to support writing and plotting solved amplitudes. * Small improvement to noise model fitting. * Run format_source.sh

Below are some plots from the unit tests, showing the removal of fake HWPSS in the template-cleaned timestream prior to final binning.
