[micro-ros] runtime toggle between comm interface (WIFI / UDP)

[shvass]

toggle between multiple communication channels available on a dev board

The Idea

• The user should be able to select communication medium from parameters
• for example WIFI, UART, USB CDC, etc
• On the next reboot , neo should try to attempt from the selected medium.

pointers

• micro-ros selects communication medium at compile time, need to figure out runtime method.
• One approach is to build micro-ros with custom comms and implement each medium ourselves.
