`picodata run --http-listen localhost` selects a wrong default port
The problem is we have a struct Address which parses from a string and if the string doesn't contain a port, it just give a default 3301 value. This value is not correct for any protocol except iproto.
We should either have the port be Option<String> or something else clever
