WIP address dateline crossing in stage_dem (#696)

* Check dateline crossing and introduce split_polygon_dateline function

* Packing together shapely imports

* Correct shapely imports

* Extending determine_projection to handle 2 polygons

* Extend download_dem to handle 2 polygons

* Extend return_dem_filepath to handle 2 polygons

* Modify overlap computation

* Correct typos

* Modify transform_poly_coords to handle list of polygons

* Fix workflow for a 1 element polygon list

* Adapt overlap_dem to handle list of polygons

* Addressing residual issue with handling list of polygons

* Modify dateline crossing function

* Optimizing code for check_dem_overlap

* Optimize return_vrt_filepath function

* Optimize download_dem function

* Fix inappropriate for cycle

* Fix pep8 notation and remove unnecessary comments

* Modify stage_dem unit test

* Compute vrt_filepath and soft failing for s3 bucket download check

* Correcting errors in stage_dem unit test

* Simplyfing list notation

* Rename poly to polys and clarifying in docstrings when list of polygons/epsg are expected

* Assert validity of inputs in transform_polygon_coords

* Generalizing for cycle in transform_polygon_coords

* Add dateline crossing and point2epsg to unit test

* Correct typo poly to polys

* Add more individual workflow checks to the unit test

* Specifying that now is list of vrt_filenames and using f string to clean up

* Clean-up generated DEM in unit test

* Correct iscetest erroneous import

* Change minX/maxX, minY/maxY variable names to abide pep8

* Remove unnecessary else/pass

* Correcting residual pep8 notation and create temp file directory with tempfile

* Add temp file to handle temporary files

* Update docstring and remove iterative dem delete

* Remove epsg check against epsg from track frame database

* Modify download_dem to accomodate new look of nisar-dem s3 bucket

* Add docstring for functions in stage_dem.py

* Correct typo in EPSG checking and change default file format to VRT

* Correct bug in check_dem_overlap

* Form VRT with datelines DEMs

* Clean up and sort inputs

* Clean up, pep8 notation, isort imports

* Correct bugs in unit test

* Switch from gdal.Warp to gdal.Translate

* Change tolerance for stage_dem.py unit test

* Download Tiff dem and form VRT. Use iterator to flag tiff files

* Check output DEM filename VRT extension

* Add extra check on EPS when crossing the dateline

* Address different epsg code for crossing dateline at the pole

* Modify lat limits for polar stereo regions

* Modify check on epsg for polar regions in unit test

* Modify outpath to guarantee uniquess of Tiff DEM name

* One epsg for polarstereo, rename epsg to epsgs, rename outdir to file_prefix

* Correct typo in epsg allocation

* Remove vrt_filename_function as not needed

* Fast EPSGs allocation using len instead of iterator

* Explictly assign EPSG since fixed

* Reduce loop in DEM download

* Simplify code in tranform_polygon_coords

* Revert chanhe in xmin/xmaxcomputation in transform_polygon_coord
