RFE: reading messages up to delimiter in a stream

[mgrouch]

A lot of streams are messages separated by sequence of delimiter characters.
it would be nice to have a reaction which can deliver to callback whole message instead of data chunk.

Something like

MessageReaction app.onMessage(Stream *stream, Delimiter delim, react_callback cb);

thanks

This is an issue that can be easily implemented downstream e.g. with SensESP transforms.
