geocode SLC integration test (#46)

* download test data from zenodo in parallel * run integration test in circleci * adding pytest as requirement and to docker specifile * updated specfile * account for multiburst, new burst ID, geocode entire burst * use main instead of tag because of missing features * clone from https not ssh * template yaml for test run * validation to check for presense of reflectors Co-authored-by: Scott Staniewicz <[email protected]>
