cargo embed rtt BinaryLE channel does not work properly

[ruabmbua]

Describe the bug

It seems like the socket feature does not work properly when setting up a RTT channel in the BinaryLE format. According to wireshark, it does not even attempt to establish a connection. The String format works fine.

Also, for me the cargo-embed console display of BinaryLE RTT data is not line wrapped. For reference, I am sending 8 byte messages in one call to the rtt_target UpChannel.

To Reproduce
Steps to reproduce the behavior:

1. Configure UpChannel 1 with NoBlockSkip on both ends, and set socket to localhost + some port, then listen on it with e.g. netcat.
   2.) Run cargo-embed in a project that sends 8byte messages as rtt data on channel 1.

Expected behavior
You will see that there is no attempt at connecting the socket. Also the cargo-embed interface for channel 1 will not line-wrap the binary data.

Desktop (please complete the following)

• OS: Linux (Arch)
• Target: RPI Pico (RP2040)
• Debugger: Raspberry PI debug probe
• probe-rs version: master (0.23)
