Release Version 0.1.0

Add Dithering option to Kmeans node

On the K-means node, I've added a dithering option for color reduction.
You can now choose between a 2x2 or 4x4 matrix, along with a selection for Dithering Strength.

Improved Clahe node  (histogram equalization)

Before the update, the CLAHE (Contrast Limited Adaptive Histogram Equalization) filter seemed to be non-functional. With this update, the filter will now operate normally. Additionally, optional value inputs (sliders) have been added to adjust the strength of the CLAHE.

• Add new test image to Test Image Input node.

That's all for the update content, thank you ~!  🥳
