Moes TRV: dp 105 is temperature calibration, add boost switch
- boost_mode was referenced but not defined
- "fill_temp" apparently means temperature calibration, and range is -9 to 9
"BoostTime" has range 100 to 900 (seconds), but function is unclear, as the other
"rapid_countdown" with range 0 - 720 min seems to be the one that goes with switch_rapid,
so left this as an attribute for now.
Issue #1780
