Some png file in my project using pngQuantize will throw `quantize failed QUALITY_TOO_LOW`

Some png file in my project using pngQuantize will throw quantize failed QUALITY_TOO_LOW, cause build failed.

can we have a fallback option that when some compress failed we can use original image or use another compress method instead(in my case, change to pngLossless worked) to make build continue?

This error comes from pngquant as png lossy compression impl of @napi-rs/image used by function pngQuantize

We can set png compress config like:

// rsbuild.config.ts
export default defineConfig({
plugins: [
        pluginImageCompress([
            { use: "png", minQuality: 0 },
        ]),
    ]
})

As I tested, quantize failed QUALITY_TOO_LOW error gone.

@Kerlli Wouldn't this allow poor quality compression to make it past the build step? From what I've seen this happens on images that shouldn't be PNG to start with - things like photos or images with complex gradiants. Better to pick jpg or webp
