use ndarray comparison options in wcs comparison

[braingram]

When comparing 2 WCS objects in the deepdiff computed between the regtest result and truth file, use the array comparison options that are used for other arrays in the diff.

These changes will mean that if both the result and truth WCS objects return nan when evaluated on the bounding box (this is what's used to compare the two objects) that the WCS objects can be considered equal if both WCS objects return the same nans.
