Initial Fan Addition

[DellanX]

I started to work on the code for the issue I created for #262, basing the logic off of the humidifier implementation.

It still needs some work integrating the MQTT class into your framework. I'm having issues getting my environment setup, but once I got it, I should be able to tackle getting a working fan device conversion.

This is about as far as I am willing to take the implementation, as I don't the time to learn how to add tests, or how to setup the build process so that I can prototype it.

Hi @DellanX, I was wondering where you ended up with this? If it adds functionality for fans, I'm thinking I could fork and apply this PR...that is, unless you have a later version or any thoughts or advice? Cheers!

I wasnt able to get the addon to build to validate my changes. Also, I think there are a few typos in there.

The main thing is, to register to a fan mqtt entity the different mqtt entities to read/update to implement a fans different features.
