An implemenmtation of a [coaphandler::Handler] around a [scrollring::Buffer]
Wrap a buffer (typically some tasks's linear text output) through
BufferHandler::new(&buf) and place it .at(&["output"],
...) some CoAP handler tree.
This crate comes with no example, but the coap-message-demos crate makes ample use of it for its logging adapter.
