feat(daizuki_heatpump): handle C version.

Based on data available, bit 21 of flags (dp 110) tells the device's native temperature unit.
The F version that this was previously for always reports C for current temperature, but
uses F for temperature. According to PR #5521, an EU version of Nordis Orion EVO (same
product id as TCL AirMax) exists with the only difference being the use of C for temperature.

Use the temperature unit flag to handle this difference so that the product id match
does not mislead users into loading the wrong config (other configs exist with basically
the same dps layout, some with the same presets and temperature range, but choosing the
right one is difficult without the automatic product id matching telling you which is the
correct on).
