add new is_constructible_* traits used in from_json
is_compatible_* traits were used in from_json, but it made no sense
whatsoever.

It used to work because of non-SFINAE correctness + json_ref
unconstrained variadic template constructor.

SFINAE checks are becoming quite complex, we need a specification of
some sort describing:

* which concepts the library uses
* how the conversion to/from json works in detail

Having such a specification would really help simplifying the current
code (as well as having meaningful checks).
