Specification of packet header for INFO responses is ambiguous

[chad-earthscope]

The current specification does not appear to specify what the sequence number and station ID fields would be for responses to INFO packets.

One could image the sequence number is 0 and the station ID is omitted or some fixed value. Either way clarity would be good for completeness, even if the values are left to the server.

[chad-earthscope]

On the point of what a station ID would be for such transient packets, it might be nice to have a fixed value here instead of empty to help downstream processors that are potentially using the value to print diagnostics, organize/save data, etc.

Perhaps a fixed value of SLINFO?

Maybe an alternative is to have the station ID for info packets be the INFO command item, so one of: ID, FORMATS, CAPABILITIES, STATIONS, STREAMS, CONNECTIONS? That at least gives something minimally useful.

Also maybe ERROR for station id in instance of J E error json response to INFO?
