Type aliases for websocket::connection

[Tectu]

Personally I don't like to see code like this in an application / outside of a library:

class my_app
{
private:
    malloy::websocket::connection<false> m_ws;
};

It is not immediately clear what this boolean template parameter does without further investigation (or simply knowing it).

I would vote for adding type aliases for client & server connections which are defined as connection<true> and connection<false> respectively.

@0x00002a any thoughts?
