Clang 10.0 / GCC 10.1 warnings on disabled exceptions

[AODQ]

There are warnings on unused variables on both clang and GCC when exceptions are disabled, just pulled from latest commit ( 43e07bb ) on develop branch.

    template<class Exception>
    bool parse_error(std::size_t /*unused*/, const std::string& /*unused*/,
                     const Exception& ex)
    {
        errored = true;
        if (allow_exceptions)
        {
            JSON_THROW(ex);
        }
        return false;
    }

GCC 10.1.0

third-party/json/single_include/nlohmann/json.hpp|5441 col 39| warning: unused parameter ‘ex’ [-Wunused-parameter]
||  5441 |                      const Exception& ex)
||       |                      ~~~~~~~~~~~~~~~~~^~

Clang 10.0

third-party/json/single_include/nlohmann/json.hpp:5441:39: warning: unused parameter 'ex' [-Wunused-parameter]
                     const Exception& ex)

Pretty sure this is because JSON_THROW is an empty macro so ex does nothing.
