Remove the dependency of scikit-image

Problem

The only operation that is required from scikit-image is skimage.transform. Therefore, it is not necessary to download the whole library for a single function. Also, the scikit-image package does not support python 3.9 yet and it is preventing us to update this package.

Todo:

• [ ] Copy the function sckimage.transform from its original source to a separate package in image-quality.
• [ ] Create a docstring to specify the original source of the function, the version of skimage and a link of reference.
