Force a dummy value for SHW in modelica loads even if not present

[vtnate]

Any background context you want to provide?

MBLv10 requires a value in the Service Hot Water column of the loads timeseries, even if it isn't used. Modelica-Builder has a feature that can update values in .mos files, so lets use that.

The UO SDK populates this column as of v0.11.0 with https://github.com/urbanopt/urbanopt-reporting-gem/pull/143. Load files generated before then may be missing this data.

What does this PR accomplish?

• Uses the modelica-builder method to set SHW load to 1/10 of the heating load or 5000W, whichever is higher.
• Improve logging a bit

  How should this be manually tested?

  Generate a model using timeseries data that does not have the SHW column populated. The updated file is modelica_project/Loads/Resources/Data/<buildingname>/<load_timeseries>.mos

@nllong You mean... have the modelica package do the modelica editing, and keep log messages consistent?
