Create a fan switch for multi speed pumps

[bmorgenthaler]

I'm running Balboa Spa client on my phone and for Pump 1 I can turn it on (defaults to low) and then also turn it to high from the iOS client, in HA I'm only given a binary switch with attributes for the speed the pump is at. Suggesting to make multi speed pumps into fans so that you can set the different speeds from HA directly.

I have tried the Fan entity in the past and did not have good results! Especially when you have to replicate to the Apple Home App. Maybe I could take another look at it! If you have any ideas/examples on implementing the Fan entity, feel free to share!
