add ClimateController and additional sensors for IRCv2

[mpcaddy]

• Made some improvements to the IRCv2
• Added the Climate Controller with events to allow for the IRC to know whether they are heating or cooling
• Also added a couple of sensors from the IRCv2 to know the override reason
• Added a switch to be able to trigger the comfort override (To mimic the button on the app)
• Added a Schedule preset to go back to the scheduled preset

May need some adjustments to the Climate Controller demand, I think it is possible to connect multiple to each IRC, so may need to track multiple demands

@JoDehli I'm pretty happy with how this is working so far, been running it for the last week. This is my first work on a homeassistant integration. Also my first time working on python code in quite a while
