getting a warning about time units

[andrewkern]

currently the sweep workflow is throwing a warning about time units that looks like this

/home/adkern/miniconda3/envs/analysis2/lib/python3.10/site-packages/msprime/ancestry.py:831:
TimeUnitsMismatchWarning: The initial_state has time_units=ticks but time is measured in generations in msprime. 
This may lead to significant discrepancies between the timescales. If you wish to suppress this warning, 
you can use, e.g., warnings.simplefilter('ignore', msprime.TimeUnitsMismatchWarning)
 warnings.warn(message, TimeUnitsMismatchWarning)

I wonder if we want to suppress this warning?

If you are using a WF model, then yes, just suppress it.
