Update calls to GWCSBlot

[jdavies-st]

The following calls to the GWCSBlot class and its methods:

niriss-wfss-simulations/wfss_simulations.py

Line 54 in 2e1a6b1

from jwst.resample import gwcs_blot

niriss-wfss-simulations/wfss_simulations.py

Line 344 in 2e1a6b1

blot_parent = gwcs_blot.GWCSBlot(ref_model)

niriss-wfss-simulations/wfss_simulations.py

Line 380 in 2e1a6b1

blot_child = blot_parent.extract_image(rate_model, interp='poly5')

should be replaced with the function

from jwst.outlier_detection.outlier_detection import gwcs_blot


    blot_child = gwcs_blot(ref_model, rate_model, interp="poly5")

The GWCSBlot class disappeared a few years ago as part of the jwst.resample subpackage.
