The build of picos

[dinosaure]

Currently, picos trusts a lot on dune and use some mechanisms which are not probably available into ocaml/ocaml which can make integrating it into the standard library more difficult. It will be really nice to keep the simplest layout possible (like a module or some modules which can be compiled and usable only via ocamlopt) to make it easier to integrate into more restricted contexts (like ocaml/ocaml or into some projects that they don't use dune).

[polytypic]

Hmm... Good point. I believe that after the extra dependencies to unix and some other libraries are dropped ( #32 ) it should become easier to build the core library although we probably still want OCaml 4 and OCaml 5 specific implementation details (as there are no effects in OCaml 4). Let's see how things look like at that point — I don't have the full design in my head yet.
