Add parsing masterboard data

[urfeex]

Extends the primary parser with MasterBoard data as documented in https://docs.universal-robots.com/tutorials/communication-protocol-tutorials/primary-secondary-guide.html#masterboard-data-sub-package-of-robot-state-message

---

Note

Medium Risk
Adds a new MasterboardData robot-state type and extends the primary consumer interface with a new pure-virtual consume(MasterboardData&), which can break downstream consumers until updated. Parsing is binary-protocol sensitive, so field/endianness mismatches could surface at runtime despite added tests.

Overview
Adds parsing and representation of the primary MASTERBOARD_DATA robot-state sub-package. This introduces a new MasterboardData RobotState with full binary parsing (including optional IMMI fields) and a toString() implementation, and wires it into PrimaryParser’s stateFromType().

Extends the visitor/consumer API by adding consume(MasterboardData&) to AbstractPrimaryConsumer and a no-op implementation in PrimaryConsumer, and updates build/test plumbing (CMakeLists.txt, test_primary_parser.cpp) with new unit tests covering masterboard parsing with/without IMMI plus minor test refactors.
