Load .json.gz files directly

Should we add support to load compressed JSON reports directly?

This simplifies loading files. Tests support this currently but not capa main.

we should be able to taste the start of a compressed file and guess if it's a JSON report without too much effort.

the logic of doing the file type detection is getting a little complex, but there seems to be good reason for it all.

i think we should consider it.

Thanks

def get_auto_format(path: Path) -> str:
