[cbegeman]

Here, we add conservation plot types for all the ocean's mass flux terms.

Testing

This analysis has been run on chrysalis including against a control run: https://web.lcrc.anl.gov/public/e3sm/diagnostic_output/ac.cbegeman/analysis/20240611.HRr5_test9.chrysalis/yrs1-10_clim1-10_conserv/ocean/index.html

@xylar Would you like to try running again with the time string fix? I think your case might be more likely to trigger an issue.

Testing

I reran the test suite after rebasing this branch onto #1010 (which includes some fixes unrelated to this branch). Results are here:

Everything looks good, notably the sea-ice time series are now plotting without error.

Thank you, @xylar!
