PrImage - Quantization and other improvements

Color Quantization Added:

• Introduced QuantizeColor to round pixel colors when enabled via Plugin.Instance.Config.useColorQuantization.

Primitives Created Counter:

• Added primitivesCreated to count and log the number of primitives created during image rendering.

Optimization:

• Integrated color quantization into pixel scaling and primitive creation process.

PrImage - Transparency and RLE

This update is focused around PNG transparency and RLE.

You can now generate images in SL with transparency. Fully transparent pixels wont generate a quad.

Last, the update introduces RLE (run-length-encoding). Which basically groups neighbouring pixels that are the same color and makes it a larger quad.

First Release

This is the first release. Dont expect it to be polished or working perfectly.
