Add Doctrine ODM types support

[IonBazan]

It would be great to see Doctrine ODM integration here.
I've used my own enum types implementation in few projects and would like to share it in a PR which will be provided later this week.

Not sure how to handle the automatic Types generation when using as Symfony Bundle.

Hi @IonBazan . This is a good idea, but I think I've never worked with ODM custom types. So I'd greatly appreciate you share your own experience 👍🏻 .
We'll see how to proceed with type generation once the base types are done.
