PositStageNet 2.03 adds a new tracker data chunk to encode per-tracker timestamp.
It also includes a complete rewrite of the sample implementation for faster computation
and detailed tracker data specification.

• Improvements:
  • Added a new tracker data chunk to encode a timestamp per tracker.
  • Added flags to trackers to know which chunk have been received
    and to avoid transmitted properties that have not been set.
  • Rewrote the whole implementation to simplify its usage and to
    lower its computational time by reduce memory allocation and copy.
    Warning: The interface changed. You might need to adapt calls to
    the library if you update from a previous version. However,
    the changes should be straightforward.
