Alternative to Async_unix.Reader, based on the low latency transport in async_rpc.

type 'a handle_chunk_result = [

| `Stop of 'a
(*
Stop a indicates that the read loop's handler consumed 0 bytes and that the read loop should stop.
*)
| `Continue
(*
Continue indicates that the read loop's handler consumed some bytes, and would like to keep reading.
*)

read_one_chunk_at_a_time ~on_chunk reads bytes into the reader's internal buffer, and calls on_chunk whenever there is data available.
