Fix: Added auto mode to fan speed map for config 30

[rweijnen]

My Mitsubishi Heavy Industries Airconditioner with airconwithme WiFi controler an auto fan speed mode. However pyIntesishome maps only this for my device: 30: {1: "quiet", 2: "low", 3: "medium", 4: "high"},

So I changed that to: 30: {0: "auto", 1: "quiet", 2: "low", 3: "medium", 4: "high"},

Here's the full json output for both my devices, both support fan speed auto, 2nd auto is currently set to auto (fan speed 0):
