voxl-microdds-agent for connection to external fcu over uart (J10)

[jon]

Hi! Problem statement: want to connect external FCU to voxl and communicate over the microdds bridge for minimal latency. In the past, I have tried to compile the uxrce-dds agent from source https://docs.px4.io/main/en/middleware/uxrce_dds but never really dove into trying to fix all the issues. I assume this is a problem you guys fixed with voxl-microdds-agent; is it possible to modify that package to communicate with an external flight controller over UART?

Other option would be docker, which I've done before, but that incurs some overhead and we're kinda maxing out the voxl, so I would prefer a native implementation.

I guess I'm just asking if this is feasible within the design of voxl-microdds-agent or if it's tailored to communicating with voxl-px4 over shared memory.
