Support for Enums

Hey,

very cool library, thanks for it.

Is there any intention to add support for Enums in order let the following code work:

from dataclasses import dataclass
from enum import Enum

from dacite import from_dict


class SomeEnum(Enum):
    FIRST_VALUE = "first"
    SECOND_VALUE = "second"


@dataclass
class DataClass:
    message: str
    value: SomeEnum


data = {"message": "hello", "value": "first"}
from_dict(data_class=DataClass, data=data)

Currently this raises

dacite.exceptions.WrongTypeError: wrong type for field "value" - should be "SomeEnum" instead of "str"

But actually it should be quite easy to do the conversion to the enum along the deserialization (SomeEnum("first") yields <SomeEnum.FIRST_VALUE: 'first'>)
