feat: add simultaneousHandlers prop

Hi! I've faced an issue with Lists inside BottomSheet, and I could not manage to make them work without adding simultaneousHandlers to every GH.
Maybe I misunderstood sth but I've tried to play around with innerGestureHandlerRefs but still, I could not make FlatList scrollable unless enabledGestureInteraction was false.

Expo example with broken and working FlatList: https://snack.expo.io/@dsznajder/bottomsheet-with-flatlist
