fable: Move fable/json/with_eigen.hpp to fable/utility/eigen.hpp

BREAKING CHANGE: This commit renames a public header file and
requires that rename your #include statements:

    - #include <fable/json/with_eigen.hpp>
    + #include <fable/utility/eigen.hpp>

Author: cassava

fable/include/fable/json/with_eigen.hpp renamed to fable/include/fable/utility/eigen.hpp
