       ## New method
       The `new` method creates a new `Connection` instance.
       It takes the following arguments:
       - `domain`: The domain of the connection.
       - `stream`: The stream used for the connection.
       - `cert_path`: An optional path to the certificate file.
       - `key_path`: An optional path to the key file.
       - `buffer_size`: An optional buffer size for reading incoming data.
       - `timeout`: The duration after which the connection will timeout.

       It returns a new `Connection` instance.
