Fixes Space load-based actuator for spaces are named based on thermal zone name #4786

@mdahlhausen @lymereJ would appreciate a review / testing from you please.
@brianlball I'm tagging you as a reviewer as you're the most familiar with this piece of code, but if you can't review I can ask someone else (@tijcolem for eg)

Pull Request Author

Model API Changes / Additions
Any new or modified fields have been implemented in the EnergyPlus ForwardTranslator (and ReverseTranslator as appropriate)
Model API methods are tested (in src/model/test)
EnergyPlus ForwardTranslator Tests (in src/energyplus/Test)
If a new object or method, added a test in NREL/OpenStudio-resources: Add Link
If needed, added VersionTranslation rules for the objects (src/osversion/VersionTranslator.cpp)
Verified that C# bindings built fine on Windows, partial classes used as needed, etc.
All new and existing tests passes
If methods have been deprecated, update rest of code to use the new methods

Labels:

If change to an IDD file, add the label IDDChange
If breaking existing API, add the label APIChange
If deemed ready, add label Pull Request - Ready for CI so that CI builds your PR

Review Checklist

This will not be exhaustively relevant to every PR.

Perform a Code Review on GitHub
Code Style, strip trailing whitespace, etc.
All related changes have been implemented: model changes, model tests, FT changes, FT tests, VersionTranslation, OS App
Labeling is ok
If defect, verify by running develop branch and reproducing defect, then running PR and reproducing fix
If feature, test running new feature, try creative ways to break it
CI status: all green or justified

+  A6; \field Zone or Space Name
+       \note This field is useful for a SpaceLoadInstance that is assigned to a SpaceType
+       \note because internally E+ will duplicate the instances and you need to access the final name
+       \note If you are using the Space Translation of the ForwardTranslator (which is defaulted on) this should be set to a Space
+       \note If not then use a ThermalZone
       \type object-list
-       \object-list AllObjects
+       \object-list SpaceNames
+       \object-list ThermalZoneNames


Constrain this field in the IDD. It will now only accept a Thermal Zone or a Space.

I didn't want to break API, but this should never have been an optional. Though I suppose the idea is that there's a chance the object it referenced would be deleted, right?

Thats right. what happens if that object gets removed?

You just don't translate it during FT. That can mean having the FT calling an Impl function or in a try catch
In an ideal world, removing à modelobject would mean removing any ems actuator attached, but that's probably a major slow down and we don't want to penalize anyone not using ems

If we are NOT translating spaces.... We construct a std::set of all the found Thermal Zone Names (so it's sorted and unique)
If we can't find any, throw. Otherwise, grab the first one, issue a warning if one only, an error if two or more

this is great work! Thank you!

Thanks @jmarrec this is helpful! I'll test it out with standards unless Jeremy Lerond beats me to it.
