Custom Swipeable component based on Sowtware Mansion React Native Gesture Handler

Based on Ver 2.1.0 (Expo SDK44 compatible)

• Added properties leftStop and rightStop. When opened passing this breakpoint (but before left/rightThreshold) opening stops there when released
• New getState() method return internal state (dirty hack, I know!)
• Methods openLeft/openRight accept optional parameter position to perform a partial opening.
• onSwipeableLeftOpen/onSwipeableRightOpen/onSwipeableOpen now provide argument toValue
• currentOffset() internal function takes last real position instead of returning full width. This was causing weird animation effect before closing
