Add ability to use compressed files in pull URLs

[jvendetti]

BioPortal currently allows end users to manually upload ontology submission files in ZIP format. However, equivalent functionality isn't present for pull URLs. If a pull URL points to a compressed file, the file is downloaded but never uncompressed. Subsequently, the parsing stage where we attempt to load the file with the OWL API fails. See the following test ontology in staging as an example:

https://stage.bioontology.org/ontologies/TESTGZIPPULL

... where the pull URL points to the following location:

https://github.com/musen-lab/hgnc2owl/raw/main/hgnc.owl.gz
