[Feat] Add event for when the resize event fires and all changes have been propagated through

[rvanhoecke]

Emitting an event after resize would allow for custom hooks after the slider has been re-initialized. This may require asynchronous methods for the the construction of the slider. I have tried to hook the .next(currentPage) function to return to the same slide after resize as it is a jarring experience for a user to be moved back to slide 1 whenever they resize the page. This could also be solved by allowing the user to specify the starting slide in the config parameters on construction of the slider. An example for the config would be
this.sliderConfig = {
all: {
slidesToShow: 1,
loop: false
startOnSlide: 5
//with this parameter you could pass a function in so the reinit would work as well
get startOnSlide() {
return getCurrentSlide();
},
},
}
