cachefile_storage accept callable which returns a storage object

[pickfire]

A storage object, or a callable which returns a storage object. This handles the storage and retrieval of your files. See Managing files for details on how to provide this object.

But imagekit only accepts a storage object. It should supports a callable which returns a storage object for feature parity with django.

So rather than doing cachefile_storage=S3Boto3Storage(), one can just do cachefile_storage=S3Boto3Storage.

django-imagekit/imagekit/cachefiles/__init__.py

Lines 43 to 45 in f6ed35f

	storage = storage or getattr(generator, 'cachefile_storage',
	None) or get_singleton(settings.IMAGEKIT_DEFAULT_FILE_STORAGE,
	'file storage backend')

Thank you for reporting the issue. Do you think that you can be able to prepare a PR with a fix for that?

I've just been trying to use this fix and it looks like the change makes the storage callable - not the cachefile_storage. Or have I misunderstood something here?

Yeah, looks like it, I noticed it in our project too but I didn't submit a pull request, supposedly it should also check if cachefile_storage is callable.
