add json_fwd.hpp from json/single_include/nlohmann/single_include directory of the nlohmann json project. Also add json_fwd.hpp wrapper in include/inja. This is a smaller include forward file suitable for use in an include file. Not needed to build but useful for code using the json library.

Hi, I've been using inja in a project for a year or so, and discovered in the upstream nlohmann/json repository the json_fwd.hpp header which is the minimal header needed to reference the json library from a header file in client code without pulling in the whole json.hpp. Here's a pull request in case it's useful for others. |
