Add support for Hydrotherm Dynamic/X8 gen 6 water heaters.

DPS layout completely different than gen 5 that is already supported.
Got full dps info, but Chinese descriptions/names conflict with
English. Chinese seem to be correct where units are given, so based
the config on those.

DPS layout is 100% match for IPS heatpump, but function is totally
different. Some of the incorrect english naming may have come from
them using the heatpump as a template.

Issue #1625
