Humidifier

[alevaquero]

What does this implement/fix?

Implements a Humidifier component. This is mostly a copy of the Climate component. The motivation was that while using a Thermostat Controller as my whole-house humidifier works fine, from the HA perspective that is still a thermostat which does not render correctly in lovelace UI (e.g. temperature units instead of humidity percentages)
