Return a state for manage loaders, untill images are not ready to use

[Muhammad-zain-rehman]

Hey! Ehsan thanks for sharing such a nice library it made my day. let me tell you a little bit of enhancement for this library that should be considered. As I'm a beginner it might be helpful for me as well.

Although it is amazing, there should be a prop that can tell us about the loading state of the images. For example, I just use this library in my project it has 400 images for one sequence, When images are loaded by the library meanwhile my screen gets blank. I'm not quite sure how I can handle this but I think whenever the images are (e.g. first image of any sequence) being loaded by the library there should be a prop through which we/I can determine and manage any loader kinda stuff.

Hi Muhammad! Yeah, you're right. I have a plan to refactor it in the future. Maybe I can handle it. Meanwhile, if you have any ideas feel free to create MR
