Bstr, Slice & Bin

This small set of libraries offers a homogeneous API between 3 types and their derivations with the slice type, as well as a small DSL for decoding "packets" (such as ARP or DNS) without too much difficulty.

The aim is to homogenize the 3 types string, bytes and bigstring and to derive them with a slice type, giving the user all the levers needed to manipulate packets, whether in the form of a bigstring, string or bytes. The slice view avoids copying when it comes to decoding a packet and extracting a sub-part. The slice also applies to bigstrings, whose Bigarray.Array1.sub is more expensive.

This set of libraries is a synthesis of [astring][astring] (which offers a range of useful functions as well as slice), [cstruct] (which offers a similar API for bigstrings), the standard OCaml library and [repr][repr] for decoding/encoding these values into OCaml records/variants.
