Feature Request

From all that I have researched, there currently doesn't seem to be a way to support x & y origin coordinates for the crop operation. I tried to work around it but it seems it would involve working on both this library and @cloudinary-util.

In my use case, I have full images that have been cropped by users, giving me x, y, width & height percentages. Working directly with the Cloudinary URLs works fine as long as I specify the percentages as percentage / 100 (x: 50% would be x_0.5).

Thank you!
