[Feature Request]Dragon Bones of the model are not imported when exporting in separate texture mode

[JekSun97]

If we export the model to Dragon Bones with the Image Type: Images parameter, and not Texture Atlas, that is, so that all textures are separate, then the plugin does not perceive them as Dragon Bones files, and does not create a dbfactory.

This method might be convenient if we wanted to change individual parts of the texture in the model, if the dragon bones API allows it.

I think it should be support, too.
But I have not time to do this, I can only focus on bug fixes.

I hope someone can participate in the code submission.
