feat(users/Profpatsch/lens): lens library for nix r/3049
Profunctor lenses for nix.

Implemented Profunctor and Strong instances for `(->)`,
and some simple setters.
Next step would be getters, which will need the `Forget` profunctor.

Fairly straightforward implementation of
https://github.com/purescript-contrib/purescript-profunctor-lenses
(with all the types erased and instance dicts passed manually).

```
> :p set (optic [_2 (field "foo") _1]) 42 (tuple 1 { foo = (tuple 1 2); })
{ fst = 1; snd = { foo = { fst = 42; snd = 2; }; }; }
```
