Update forge, tig, and forge-py to handle when empty granules come in

[jamesfwood]

Tig seems to hang and time out, and forge fails.

We want to check if the input granule is empty at the beginning and handle this problem gracefully.

Just fail fast and report the reason for failure right away.

Update forge, tig, and forge-py.

Address this issue:
https://jira.jpl.nasa.gov/browse/PODAAC-6139
and this:
#28

Update to work for both backfill-tool and Cumulus
