Draft: wallpapers/color: simplified better accent color generator

The accent color is extracted using the Android method, which includes:

1. Wu's quantization algorithm
2. K-Means for color quantization by Celebi
3. Color scores based on hue proportions and chroma.

Then a dominant color is extracted from the clusters, and the final color will be adjusted to be not too dark or too light. If the color collection is empty, the default Breeze Blue color will be used.
