[JonatanAntoni]

Contributes to #27

  - ctrace-ref: data#1
    type: dwt
    address: <fixed or resolved symbol address>
    size: <fixed or resolved symbol size>
    symbol-file: <symbol file if used>
    data-type: <symbol type>

Tested briefly. This should keep us going. Some adjustments needed/to be considered as we go forward. Split into things that would be awesome to get fixed now (or soon), and things that would take a little longer.

Action now if possible:

• I get data-type = unsigned int for osRtxInfo.kernel.tick. Should be unsigned.

Action later:

• If I use an object like osRtxInfo then I get data-type = object. Should default to unsigned but not yet documented. Leave as is for now in case I can think of why object as data-type would become useful.
  • Update: object becomes struct with changes in Enhance dwarf reader to return canonical type names #31
• If I enter a size of 6 then I get the error: error: Cortex-M7 DWT-Unit data.size must be a power of two. In future we must auto-expand to satisfy the HW needs and write a warning. See Unexpected output for data: entry with size #19 .
