Data Fields consist of a key / data pair, where the key contains metadata for the length of the field
and the Field ID (FID) of the field. The key is followed by the actual data of the field.

The data can be a structure containing multiple values.

This allows for a flexible record where new data types / structures can be added to the system and
the metadata in the key allows it to be backward compatible with parsers. Fields can also be
repeated multiple times in a single record if required, for example fuel readings from 2 fuel tanks.

Integrators will note that some of the fields have been deprecated. Others are rarely used, and use
depends on the device type. It is worth discussing which fields to prioritize with a Digital Matter
Engineer.
