Infinite scroll for multiple images

[furkankurt]

Description

By default, PageView.builder is infinite in Flutter, unless you provide an itemCount.
I added an option to use the infinite scroll feature for the EasyImageViewPager widget.

You can use infiniteScroll: true to create a "looping" effect with the images. This means that when you reach the end of the image list, you will be taken back to the beginning. This can be useful if you have a small number of images and want to allow the user to scroll through them continuously.

This PR covers the closed issue #42

@furkankurt Thank you for such a diligently put-together PR. Could you change it so it just contains the infiniteScroll changes? We don't want to update the minimum Dart or Flutter version for this change. Thank you so much. Once that's done, I'm happy to do a code review. Thanks again!

Hello @jfahrenkrug, thank you for your comment.
I'm looking forward to seeing your review and acceptance, and I hope you will create a new release on the pub.dev as fast as well 💯

@furkankurt Thanks so much for your great work. All tests pass. I have just one small nitpick request: Could you rename infiniteScroll to infinitelyScrollable? Since we already have swipeDismissible and doubleTapZoomable, it would fit better into the naming pattern. Thank you! I also really appreciate the test coverage. This is a truly exemplary PR!

@jfahrenkrug thank you, I will update it as soon as I available.

[jfahrenkrug]

Thank you @jfahrenkrug, when will you be able to create another release on pub.dev?
