aider: Corrected dialing of the RELP server by parsing the URL, ensuring the scheme is "tcp," and extracting the host and port for connection.

# Aider chat conversation:

USER: you are dialing r.relpServerURL directly.  this is incorrect as the variable contains a URL, not a bare host:port.  please parse the url, ensure the scheme is tcp, and extract the host and port for connection.

ASSISTANT: To correct the dialing of the RELP server, we need to modify the `connectToRELPServer` method in the `relp_handler.go` file:

1. Parse the URL.
2. Check if the scheme is "tcp".
3. Extract the host and port for connection.

Here is the *SEARCH/REPLACE* block:

	return conn, nil
