Updates quickstart figures using current code version so that users don't worry about differences between their results and those on the quickstart docs.
Reduces the number of warnings and adds note about expected warnings in quickstart tutorial.
Carries the centroid_sx from S3 photometry through to S4 (previously was forgotten, so it was unavailable in Stage 5).
Implements the NIRCam longwave wavelength solutions using a polynomial fit computed by Everett Schlawin (@eas342) for F322W2 and F444W. These can be used by setting meta.poly_wavelength=True, otherwise the values in the FITS files will be used. This new meta parameter has been documented in the ECF docs and is assumed to be False if not put in the ECF.
