Change Description

Add a U8 array to CmdSeqIn to allow pass through arguments from SeqDisp to CmdSequencer / FpySequencer / etc

Rationale

This is a feature to pass through arguments from the SequenceDispatcher to Sequencers (current and future) that support it.

Testing/Review Recommendations

Ensure SequenceDispatch functionality is working, both on fprime and fpy side.
These changes should not break / altar core functionality.

Future Work

This is a chain of pull requests to support arguments in sequences. Future work includes:

• Creating a tool to pass arguments to the GDS to start a sequence with arguments
• Fpy#30 Future Work: Replacing arguments onto the Fpy stack
• Discussion on call syntax for sequence with arguments within sequences
• Documentation

AI Usage (see policy)

Claude Code v2.1.92 sonnet used to autocomplete and find instances where CmdSeqIn changes were required.
FPP coding was done by hand and claude was used to autocomplete C++ calls.
All lines of code were human reviewed.

So is modifying the RUN going to be a separate PR? Why not just do it in this PR, I think they are related. New RUN_ARGS cmd for SeqDispatcher and update existing RUN cmd for FpySeq

Port buffers approved.

Spectacular work! Let's merge it.
