When comparing this week's cylc run to last week's run, provide an email address to get alert emails if the BinValAxes2D RMS variances are too large.

Description

This PR modifies the script which is run every weekend by the cron server.
The script runs a weekly cylc job, then it is run again to graph the results, comparing to the previous week's run as well as comparing to a baseline run (currently results from running mpas-bundle release 3.0.2).

This change adds an optional run time parameter of a comma delimited list of email addresses which will receive an alert email if variances between this weeks run and the previous weeks run are too large.
Note that comparisons between the current run and the baseline are not checked.

See https://github.com/JCSDA-internal/mpas-jedi/pull/1155 for the actual mechanism which sends email(s).

Tests completed

I modified the cron job to provide my email address when creating graphs. I verified the variances were checked (by looking at logs).
