Dr Heater DR008 Thermostat: changes from review

- split preset_mode out from unnatural mapping to hvac_mode inherited from JIahong thermostat.
- follow naming convention
- use translations where possible
- follow Jiahong for "energy" sensor. Apart from temperature range and a couple of missing dps, they are identical, so this is likely a run time sensor which combined with "calibration" (wattage) can be used to calculate energy as per Jiahong, rather than a direct energy reading.
