Added utils.py functions to load WAS OPD and interpolate them to WebbPSF's expected size.

Just change the instrument OPD like so:

nrc.pupilopd = webbpsf.utils.load_was_opd(nrc, fitsfile)

where "fitsfile" is the input WAS OPD. Then, create a PSF like you normally do.

Please let me know if you think there is better place for these two functions to live.

I made the recommended changes, along with a few bug fixes and additions. The functions now live in webbpsf_core.py, under the JwstInstrument class.
