Protocol version incorrect for ros noetic

[dimitriasilveria]

In the ros noetic node_handler.h function, the protocol version is number 2, corresponding to hydro distro, causing a mismatch in protocol version error in noetic.

Can you please go into more detail, where this causes an error and how to fix it? (also the file is called node_handle.h, without the r)
