Check the circularity of the occulter

[mgalloy]

The pipeline should occasionally check the circularity of the occulter by not using the CIRCULAR keyword to MPFITELLIPSE. This would not take a lot of time, so it could be done for every file. For example on 20220901, the profiler says:

MPFITELLIPSE, 280, 0.020238, 0.398555, 0

So it only takes 0.4 sec currently to do 280 center findings.

• [ ] produce a warning/error in the log if the eccentricity is too high.
• [x] report (in FITS headers and database) eccentricity in each camera.
• [x] report (in FITS headers and database) angle of major axis

17e8dd97e16ca2889a77999e785f5fe961cfd50e adds eccentricity to FITS headers and database.

76dce34bc13317232fe570ceff43b4e9719d2089 plots the eccentricity and ellipse angle daily.

Still need a cutoff threshold to produce a warning for.

It would be good to produce some summary plots after reprocessing the entire mission.
