      Bytesrw extends the OCaml Bytes module with composable, memory efficient,
      byte stream readers and writers compatible with effect-based concurrency.

      Except for byte slice life-times, these abstractions intentionnaly
      separate away ressource management and the specifics of reading and
      writing bytes.
