Describe the bug
For the two SLCs near the dateline, the asf_search gets coordinates within longitude +/- 180 and so the contiguous polygon we are looking at spans the entire globe 😢

The MWE is reported in asfadmin/Discovery-asf_search#163

To Reproduce
Use SLC IDs:

reference: S1B_IW_SLC__1SDV_20211222T054456_20211222T054526_030134_039920_9391
secondary: S1B_IW_SLC__1SDV_20201215T054451_20201215T054521_024709_02F04A_6033

We could write some basic control flow to update the geometries here: https://github.com/ACCESS-Cloud-Based-InSAR/DockerizedTopsApp/blob/dev/isce2_topsapp/localize_slc.py#L86-L87

We can fix the metadata issue first identified above (as done in #81), but the ISCE2 processing does not complete even with bounds correctly over the dateline. Leaving this open - we should address the processing issue directly in ISCE2.
