This tool can be used to connect to an arbitrary WebTransport server.
      It has several limitations:
      
        - It can only send an entirety of a stream at once.  Once the stream
          is opened, all of the data is immediately sent, and the write side of
          the steam is closed.
- This tool does not listen to server-initiated bidirectional
          streams.
- Stream IDs are different from the one used by QUIC on the wire, as
          the on-the-wire IDs are not exposed via the Web API.
- The WebTransportobject can be accessed using the developer console viacurrentTransport.
