geolocate_uavsar hanging

[jacktarricone]

@ZachKeskinen @rpalomaki Issue with geolocate_uavsar. Maybe test it out on your local machines and see if it will work? It produced the llh .tifs, but then isn't ingesting them to the geocodeUsingGdalWarp function.

@jacktarricone Can you upload the exact files you are using to a directory somewhere so we can test? Maybe a new folder at tests/data or something?

[jacktarricone]

@rpalomaki Data is on the google drive here, and this ISCE script of how I generated the unw file https://github.com/SnowEx/uavsar_snow/blob/main/examples/snowex_isce_uavsar_processing_tutorial.ipynb

I broke geocodeUsingGdalWarp out into pieces and tried running each separately. Everything works until the gdal.warp at the end. Given we didn't change anything and it was working in uavsar_snow and my local nb, do we think this is possible a gdal bug? I'm going to try going down to past versions of gdal to see if it works.

[jacktarricone]

Update - It finally ran but took 20 minutes. I'm not sure why given it used to take maybe 20 seconds with larger datasets.

Even when going back and rerunning the code in https://github.com/SnowEx/uavsar_snow/blob/main/examples/carc_geolocate_test.ipynb, it's still taking a long time.

@ZachKeskinen did you change anything when importing into uavsar_pytools? I wouldn't imagine so and therefore am caused what could be causing the slowdown..

[ZachHoppinen]

I don't think so, I think the only pieces I might have changed would be all file io so shouldn't affect geocoding.

versionwise it was working with gdal == 3.0.2 on my computer when we were testing.
