Obtain or generate NIRCam WFE maps for coronagraphic field points

[mperrin]

Either find WFE maps from the IPR LEDs, or generate from Zemax.

This should hopefully include wavelength-dependent terms for the NIRCam-internal WFE (from the refractive optics being used at large field angle), and also for the wedge chromatic term. (see also #115)

Should have tagged @JarronL in this issue too

@JarronL I also wanted to ping you again on this one. It sounded like you could help provide us with info for the field dependent WFE terms and other factors for the coronagraph field points. Is that something you could provide in the near term? We're hoping to get a next release out timed for the June AAS meeting incorporating CV and OTIS results, etc, and could include this in that.
