Occasional "b2.exception.DestFileNewer: source file is older than destination" error

[anthonyfok]

Will notified me of two GitHub Actions error as seen at https://github.com/OpenDRR/opendrr-data-store/actions, in particular:

• https://github.com/OpenDRR/opendrr-data-store/runs/2605540488?check_suite_focus=true#step:16:52
• https://github.com/OpenDRR/opendrr-data-store/runs/2605766714?check_suite_focus=true#step:16:52

It turns out that the Backblaze B2 tool errors out occasionally when it detected the source files being older than what is already on the B2 bucket:

  File "/usr/lib/python3/dist-packages/b2/sync/policy.py", line 99, in files_are_different
    raise DestFileNewer(
b2.exception.DestFileNewer: source file is older than destination: local://view_outputs/all_indicators/multi_hazard_threat/economic_region/nhsl_hazard_threat_all_indicators_b_1010.zip with a time of 1621298707917 cannot be synced to b2://view_outputs/all_indicators/multi_hazard_threat/economic_region/nhsl_hazard_threat_all_indicators_b_1010.zip with a time of 1621299046514, unless --skipNewer or --replaceNewer is provided
ERROR: source file is older than destination: local://view_outputs/all_indicators/multi_hazard_threat/economic_region/nhsl_hazard_threat_all_indicators_b_1010.zip with a time of 1621298707917 cannot be synced to b2://view_outputs/all_indicators/multi_hazard_threat/economic_region/nhsl_hazard_threat_all_indicators_b_1010.zip with a time of 1621299046514, unless --skipNewer or --replaceNewer is provided

Issues:

• The "GeoPackage exports" GitHub workflow, which takes 4 hours or so to run, is being triggered on every single push and pull request, and that is probably too frequent.
• With it being triggered on each push, and each instance taking 3 or 4 hours to run, when there are multiple pushes in close succession, more than one instance might be trying to uploading to B2 bucket at the same time.
• The error avoids a race condition, so it is "good".
• The error message can easily be overridden with --skipNewer or --replaceNewer, but there should be a better way to resolve this issue.
