Support for image-rendering: pixelated

[volkyeth]

Feature Request

Description

When using upscaled png images, specifically ones including pixel art, I want to be able to use the css style image-rendering: pixelated to make the image crisp (make it use nearest neighbour scaling)

Additional Context

Currently that style has no effect, and upscaled pixel art images get blurry. The workaround is upscaling them with something like https://github.com/lovell/sharp before using with Satori.

I don't think there's an equivalent API inside SVG's <image> element (https://developer.mozilla.org/en-US/docs/Web/SVG/Element/image), so the end result of Satori can't have pixelated images embedded. Thanks for the idea though, I'll move this to discussions until we have a clear path on how this can be supported.
