Implementing custom transports for Zenoh-Pico

[raitzjm]

How feasible is to write a custom transports for Zenoh pico? In my case I am interested in writing a CAN-FD transport. In micro-ROS with Micro XRCE-DDS it was quite simple for me to do it, just had to write definitions for an open, read, write , and close functions. I looked at the code in the Zenoh-Pico repo, but I cannot find a common structure or interface to do it as I did in micro-ROS, it looks like there is a lot of places where I need to write custom code. What are the steps or requirements to add another transport?
