Add APIs for automated parsing of payload data in Qt CAN bus, especially DBC

Currently Qt CAN Bus API covers all aspects of connectivity and handling packets.
Users still need a support for a comfortable parsing of the payload data.

One of the most popular data formats is DBC. DBC is a format specification which describes how the payload data on the bus can be mapped to various data fields. In a simplified form, it is a kind of format for name-value pairs.
It would be helpful to have a component which would be able to take a description of a name-value pair data stream as input, and use it to automatically convert this input to value-types in Qt, for example a QMap or a QJsonArray, and create names mapped to named used the name-value pairs. There is an internal prototype once made for a customer request for this which this can base on. Morevoer, several other protocols mentioned in the epic          Additional CAN Protocols

can be handled in a similar form, if we would request a user to write a name-value pair list for a given usecase. More information about DBC can be found here: https://www.csselectronics.com/pages/can-dbc-file-database-intro
