A dictionary of which the key indicates the field type. These regex values
correspond to one of dsmr_parser.obis_reference constants.
The value is either a CosemObject or MBusObject. These have a 'value' and 'unit'
property. MBusObject's additionally have a 'datetime' property. The 'value' can
contain any python type (int, str, Decimal) depending on the field. The 'unit'
contains 'kW', 'A', 'kWh' or 'm3'.

Telegram as an Object
--------------------- ---------------------
An object version of the telegram is available as well.
A Telegram has attributes for all the parsed values according to the given telegram specification. Each value is a DsmrObject which have a 'value' and 'unit' property. MBusObject's, which are DsmrObject's as well additionally have a 'datetime' property. The 'value' can contain any python type (int, str, Decimal) depending on the field. The 'unit' contains 'kW', 'A', 'kWh' or 'm3'.
Note: Telegram extends dictionary, which done for backwards compatibility. The use of keys (e.g. `telegram[obis_references.CURRENT_ELECTRICITY_USAGE]`) is deprecated.
Below are some examples on how to get the meter data. Alternatively check out the following unit test for a complete example: TelegramParserV5Test.test_parse
