Cross stitch face pattern finder

**Is your feature request related to a problem? Please describe.**
Cross stitching is a form of embroidery that involves creating decorative patterns or designs by sewing X-shaped stitches onto fabric. When you want to create an embroidery of a person you'll have to first create a simplified sketch of it ie...you can't embroide that image with the same exact colors, cause there'll be a lot of them. Take a look at this image, we can see that this image consist of a lot of colors. Its difficult to embroide this person

**Describe the solution you'd like**
The above mentioned problem can be solved by using machine learning ie.. the K means algoritm can be used to reduce the complexity/no0fColors by image quantisation. The number of colors and the desired image size can be given as an input (note that if you have a embroidery frame with a holes then you shall pass in 100 as size, here is an example for size:100 and 50, colors=5)
