Pull Request Description

Improve/clarify names for options:

• "ASHP, SEER 16, 9.2 HSPF, Integrated Backup, 5F-40F switchover band" to "ASHP, SEER 16, 9.2 HSPF, Existing Backup, 5F-40F switchover band"
• "ASHP, SEER 16, 9.2 HSPF, Separate Backup" to "ASHP, SEER 16, 9.2 HSPF, Existing Backup"
• "MSHP, SEER 16, 9.2 HSPF, Separate Backup, Max Load" to "MSHP, SEER 16, 9.2 HSPF, Existing Backup, Max Load"

For these options, set:

• heat_pump_backup_type=auto
• heat_pump_backup_fuel=auto
• heat_pump_backup_heating_efficiency=auto

Remove all the (obsolete) "Dual-Fuel ASHP, SEER 16, 9.2 HSPF, Integrated Backup, xx% AFUE xx, 5F-40F switchover band" options from the lookup.

Move heat_pump_backup_use_existing_system argument assignment from parameter Heat Pump Backup to HVAC Heating Efficiency. For each of the above options, set it to true. Delete the Heat Pump Backup parameter row from the lookup.

A Required argument 'heat_pump_backup_fuel' not provided for measure 'BuildResidentialHPXML'. error will now be thrown when trying to use, e.g., the "Dual-Fuel ASHP, SEER 16, 9.2 HSPF, Existing Backup, 5F-40F switchover band" option without heat_pump_backup_use_existing_system=true.
