Support Optional ignoreGestures Prop

[mdaronco]

See original PR here.

• Adds support for an optional ignoreGestures boolean prop that will prevent PanResponder pan handlers from being set on the View. This is suitable for use cases where fixed session durations are desired.
• Converts the FC to a pure component using the memo React HOC to prevent needless re-render cycles.
• Updates UserInactivityProps to extend ViewProps for enhanced custom View control
