INSAR_ISCE_BURST jobs fail with errors such as RuntimeError: S1_320206_IW1_20200901_20200913_VV_INT80_77F1/S1_320206_IW1_20200901_20200913_VV_INT80_77F1_unw_phase.tif, band 1: Failed to compute statistics, no valid pixels found in sampling. during the geocoding step when a user processes a pair of scenes entirely over water and applies water masking.

For example, this pair is off the Florida coast:

S1_320206_IW1_20200901T232050_VV_8BB7-BURST
S1_320206_IW1_20200913T232051_VV_DD3A-BURST

I think this is the same bug as https://github.com/ASFHyP3/hyp3-isce2/issues/247 The lonlat coordinates are wrong, so that pixels in the water mask cannot be correctly transformed from wgs84 to radar coordinates.
