[Bug]: Offset between bursts in final velocity field #706

Checked for duplicates

Yes - I've already checked

Describe the bug

The interferograms stitching/unwrapping in dolphin fails for some scenarions combining more that one burst. After processing a few orbits covering an study area, the final velocity field show offsets at the merging line between burst and/or in the overlapping area relative to the rest. I assume this is coming from stitched interferograms with phase inconsistencies that cannot be resolved by the unwrapper.

What did you expect?

Any idea/suggestion on what the root source could be and how to fix for that?

Reproducible steps

Processed several orbits in ascending and descending and problem persists

Environment

Please paste the output of the following:
`python -c "import dolphin; print(dolphin.show_versions())"`
...
dolphin version: 0.42.4.post1.dev3+g7c7819646
