Improve ImageFeatureExtraction rerender performance

[sabman]

Improve the performance of onmouseover in the src/app/tasks/image-feature-extraction/page.tsx under the src/components/tasks/image-feature-extraction/ImageFeatureExtractionPrecomputedSimilarityLayer.tsx component is slow to rerender the colors.

Debounce doesn't help a lot. The performance might be related to maplibre-gl's rendering speed for large number of features in mvt layer.
