[Feature Request] Remove setTimeOut from steps

[twjasa]

Hello,

amazing project!! 🙌 I want to create a feature that can show to the user what is the best set available for the image selected, how many sets needed and which is the cheapest.

Is your feature request related to a problem? If so, please describe it.
To create an algorithm to do that I had to fix the problem where the steps were before a setTimeOut, so here it is :)

Describe the solution you'd like
I used the method ready() of the lib cropperjs to detect when the input is finally loaded, then create a flag to run (or not) run step1. then remove all setTimeOut.

Here is the PR
