Android Image Cropper async support and custom progress UI

It's embarrassing really, soon after creating my Android-Image-Cropper fork as I wrote about in my previous post, a GitHub user noted that I have a slowness issue caused by loading/decoding image URI on main thread potentially causing an ANR, really a newbie mistake.
