Description
I implemented a stop-gap solution to DM-16235 (using the original calibration for the mean calibration so that mean calibrations are never negative). This ticket is to finish the integration code that was started there, so that we can compare the jointcal means with the original processCcd calibration means.
Jim Bosch suggests using the Chebyshev1dBasis in lsst.geom.polynomials to help implement the integration code.

Jim Bosch: do you mind looking at this medium-sized review? It's about 250 lines of important changes: it'll be clearest if you do it by commit, since some of the commits are just renames and/or a bit of post-
DM-13976cleanup.You had some suggestions about how to use the recurrence relations in the new polynomials code, but I wasn't sure how to go about it, so feel free to put those in the review.
