Add the public ASF Earthdata Cloud HTTPS distribution to the dem/watermask staging scripts behind a -s/--source {s3,https} flag, defaulting to the existing S3 behavior. This enables users to run the scripts from environments outside AWS where direct S3 bucket access to denied. HTTPS requires a NASA Earthdata Login (EDL) account and a ~/.netrc entry.

Examples:
Processing from AWS onDemand system:
python -m nisar.workflows.stage_dem -p [RSLC file]
or
python -m nisar.workflows.stage_dem -p [RSLC file] -s s3
Processing outside:
python -m nisar.workflows.stage_dem -p [RSLC file] -s https
