Migrate STIPS from using an oversampled but static PSF to using an ePSF #155

In order to provide accurate source centering and improved accuracy, STIPS should use a PSF model that can be fit to sub-pixel location. The preferred solution for this is to use an ePSF derived from an oversampled PSF grid. This issue will be used to track progress in implementing this feature.
