=============================================================================
Make a frigcal source-code package (a zipfile scrubbed of private content).
This is just a few moves and a zip; there are no frozen builds here.
Unlike the app/exe scripts, this may be run on Windows, Mac, or Linux.

*NOTE*: remove any unzipped app/exe folders in build/ before running this.

[may22] Updated for new macOS build machine: republish source-code package
with an import patch in pytz/lazy.py for a Python 3.10 change and breakage.
