openstudio_results Zone Equipment Detail section fails with ZoneHVACLowTempRadiantVarFlow

[eringold]

OpenStudio 3.2.0 made the OpenStudio::Model::ZoneHVACLowTempRadiantVarFlow methods coolingCoil and heatingCoil return optional HVACComponents.

The openstudio_results resource file Siz.ZoneHVACLowTempRadiantVarFlow.rb calls those methods without checking if the coils are initialized, leading to an undefined method error:

openstudio-common-measures-gem/lib/measures/openstudio_results/resources/Siz.ZoneHVACLowTempRadiantVarFlow.rb

Line 39 in 33e9371

if coolingCoil.maxWaterFlowRate.is_initialized

Resource file needs updating (maybe with a version check?) to properly handle the optional return types for those methods.
