websockify dropped support for text frames awhile back [1][2], possibly
as of version 0.9.0 [3]. Attempts to send text frames to a sufficiently
new websockify server result in the following error returned:
Unsupported: Text frames are not supported
and then the server closes the connection.
This changes the client to call Webocket.send_binary() [4] instead of
Websocket.send() in order to send binary data rather than text.
websockify has (always?) supported receiving binary data so this should
be backward compatible with older versions.
