Example of how to use Boost.Describe descriptions as a way to map aggregates

See tests/src folder for a working example

Requires C++17 and uses [DAW JSON Link](https://github.com/beached/daw_json_link) v3 and [Boost.Describe](https://www.boost.org/doc/libs/1_79_0/libs/describe/doc/html/describe.html)

To describe a struct, only public members are supported, see the Boost.Describe documentation. It will be similar to

```cpp

struct X {

  int m1;

  int m2;

};

BOOST_DESCRIBE_STRUCT( X, ( ), ( m1, m2 ) )

int main( ) {

  std::string_view json_doc = R"json(

  {

    "m1": 55,

    "m2": 123

  }

  )json";

  auto val = daw::json::from_json( json_doc );

  assert( val.m1 == 55 );

  assert( val.m2 == 123 );

  puts( daw::json::to_json( val ).c_str( ) );

}

```

The specialization of `daw::json::use_boost_describe` is necessary. After this from_json and to_json will work with the

mapped type
