Following this ticket: mvrdevelopment/spec#255

As a first step we extended the wheel slot definition in the GDTF specification. The changes are already merged to the "next" branch of the specification.

To continue this development with a proof of concept, we would need an implementation of the changes in the library in a dedicated branch.

The changes to the specification were merged with this pull request: mvrdevelopment/spec#305

Hi, @danielmuellerma

Can you please clarify a little what I need to know about the implementation, as it wasn't clear to me from the tickets. We can also have a short meeting if you think it would be easier.

First step, WheelSlot new params, implemented.
