Update calibration coefficients to PATMOS-X version 2023.

I've declared them "provisional", because MetOp-B visible channels are degrading and the PATMOS team is investigating the issue. Service alert by EUMETSAT from 2023-08-15 (https://uns.eumetsat.int/?filter=metopbavhrr):
Edit: As requested by @kgkarl I set S1=0.1 for channel 3a on NOAA-15 (instead of zero). So pygac can at least produce finite results for the small periods where channel 3a is active. This deviates from the original PATMOS coefficients.
