Allow de/serialization of Maps

I'm willing to contribute to bringing this feature around, just let me know if I have the green light.

See, I'm using owl to build an OpenAPI specification library, but the specification declares several fields that can best be expressed as Dart Maps. Example:

Map<String, SecurityScheme> securityDefinitions;

I've wound up using @Transient() or @JsonField(native: true) and writing manual code in a fromMap factory constructor or the toJson method. This is very tedious, and can indeed be automated. Something like:

// parse(map)
object.securityDefinitions = map['securityDefinitions']?.keys?.fold(
  {},
  (out, k) =>
    out..[k.toString()] = SecuritySchemeMapper.parse(map['securityDefinitions'][k]));

// map(object)
return (new _owl_json.MapBuilder(ordered: false)
          ..put('securityDefinitions', securityDefinitions.keys.fold(
            {},
            (out, k) =>
                out..[k] = SecuritySchemeMapper.map(securityDefinitions[k]))))
        .toMap();

For conveniency's sake, it might be a good idea to switch to using package:code_builder. This would also make it possible to generate something for this field:

Map<String, Map<String, Operation>> paths;

If you feel like this would be a good addition to owl, please let me know, and I will get right to it.

Dart 2 Compatability

I'm using this library indirectly with spotify-dart in a Flutter app that is AOT compiled with Dart v2.0.0-dev.67.0, but compilation fails because of Dart 2's strict types due to the dynamic type parameter generated in json_generator.dart:81.

i.e. (map['${field.keyName}'] as List<dynamic>)?.map(${field.parserFn})?.toList()

Flutter compiler error:

compiler message: file:///Users/chancesnow/bin/flutter/.pub-cache/git/spotify-dart-55bff18594c7337681570999f994bdf8cf42b0ba/lib/spotify_io.json.g.dart:129:59: Error: The argument type '(dart.core::Map<dart.core::String, dynamic>) → spotify::Image' can't be assigned to the parameter type '(dynamic) → dynamic'.
compiler message: Try changing the type of the parameter, or casting the argument to '(dynamic) → dynamic'.
compiler message:         (map['images'] as List<dynamic>)?.map(ImageMapper.parse)?.toList();

I've tried changing List<dynamic> to List<Map<String, dynamic>> in my fork of Owl to no avail:

I've tried upgrading analyzer, build_runner, and source_gen to their latest versions for the owl_codegen package to no avail. (Same errors as above.)

I'm not sure what else to try. Any ideas?
