Make customArrows option be accessed through all events

[vuquangpham]

Problem

Flickity Responsive doesn't hide custom arrows when the slider is not slideable while we already had this function.

Why

In the responsive-navigation function, we only hide the customArrows through options.customArrows, but this option is created in onMatched event and we invoke this function inside onLoad and onResize events. So that we don't have anything change.

And a small notice that the object between each event is different in memory. So that the customArrows option that we created in onMatched doesn't exist in onLoad and onResize events.

Solution

• Make the option customArrows to be part of the Flickity instance, so that it will be accessed through all the events (onLoad, onMatched, onResize).
