Cache PSF

1. Cache at least for current ra, dec, band, pointing, sca.
2. Cache for ra, dec, band, sca. Rotate WCS of PSF as necessary to match pointing.
3. Cache base for sca, band. Calculate PSF for x, y from ra, dec. Rotate WCS of PSF as necessary to match pointing.

@laldoroty Okay, I've started by just adding the simplest caching, which just use the existing saved PSF file when it exists.
