* add miot_info() to get the common information from the device
  * this includes manufacturer, model, firmeware version and serial number

* add get_properties_for_dataclass(cls) which allows easy implementation for get_properties mappings
  * each field() can define metadata containing siid and piid, these are mapped automatically to the response container
  * _siid can be used to define common siid, _max_properties can be used to set number of maximum properties per request

* get_properties_for_mapping() requires explicit passing of the mapping, no more passing over __init__
