ewoksscxrd.tasks.utils.subtract_frame_inplace(frame, scale_factor, dectris_masking_value)

For each pixel in a frame:

• If frame[1] > dectris_masking_value, set result = frame0 + frame1 (saturating at max).

• Otherwise, result = frame0 - scale_factor*frame1 (clipped at 0).

• Finally, any input pixels that were already max uint32 in either frame0 or frame1 are forced back to max in the result (propagated).
