implement ghost style prop

[corupta]

implemented a new style prop for AnySize component, to change the style of the item that's being moved (the one in background)

my use case: I wanted to keep opacity 1 for the flying item, but 0.5 for the one in background.

thanks for implementing this package btw, it is solving a huge problem for me, I can use it in a hacky way to implement nested drag-drop functionality. If anyone wishes, I can share my hacky wrapper as well but might need to clean it first.

Update: released my hacky wrapper, fyi react-native-nested-dnd
