[WM-Bus] Add support for TCH Hardwareversion 57 device (Heat_Meter?) 

This device is recognized as OTHER. If manually set to HEAT_METER it wants an encryption key, but in my case this device sends without encryption. This could not be changed (Encryption), so no chance to get this working.

Its a Kamstrup multical21 Device I believe. There are so many distributors for same device.
