MM100 EMS+ Status Message support added

[kstaniek]

I have added support form EMS+ Status Message form MM100 modules

(01:28:57.393) 0x21 -> all, type 0x01D8, telegram: 21 00 FF 00 01 D8 00 02 00 00 EE 00 00 00 03 (CRC=C9) #data=9

00 EE -> 238 -> 23,8 C

(01:28:25.489) 0x20 -> all, type 0x01D7, telegram: 20 00 FF 00 01 D7 00 02 00 00 F1 00 00 00 03 (CRC=21) #data=9

00 F1 -> 241 -> 24,1 C

Those values represent the egress water flow temperature from a MM100 mixing device.

Changed the Info output:

Mixing module stats:
  Switch temperature: 22.7 C
  Mixing Circuit 1
   Current flow temperature: 21.8 C
  Mixing Circuit 2
   Current flow temperature: 21.0 C

I think switch temperature is available when you have configured boiler to take temperature from external switch thermometer. Therefore if you have a switch then you have to have MM modules. So it is logical to group those values together.
