Deserialization fails when using [enumConverterNumeric]

[caneva20]

Hi @k-paxian!

Today I faced a problem when using a custom enum converter. If you configure the mapper to use enumConverterNumeric and then try to deserialize the json value it fails.

Minimum reproducible code:

Enum:

@jsonSerializable
enum MyEnum { valueA, valueB }

void main() {
  initializeJsonMapper(adapters: [
    JsonMapperAdapter(
      converters: {
        Enum: enumConverterNumeric,
      },
    )
  ]);

  var json = JsonMapper.serialize(MyEnum.valueA);

  //This fails
  var myEnum = JsonMapper.deserialize<MyEnum>(json);
}

This code throws:

E/flutter ( 6045): [ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: type 'String' is not a subtype of type 'MyEnum'
E/flutter ( 6045): #0      JsonMapper.deserialize (package:dart_json_mapper/src/mapper.dart:59:5)

Thank you for letting me know. Should be fixed now.
