Bun.Image: missing support for raw pixel output

[basst85]

I’ve been experimenting with Bun.Image for an ESP32/LVGL image pipeline, and one thing I’m currently missing is support for raw pixel output.

Bun.Image is already very useful for decode, resize, and re-encode workflows, but it seems to stop at encoded output formats like JPEG, PNG, WebP, etc. What I need in this case is access to decoded pixel buffers, similar to what sharp provides with:

sharp(input)
.resize(width, height)
.ensureAlpha()
.raw()
.toBuffer({ resolveWithObject: true })

That returns raw pixel data plus metadata such as width, height, and channel count, which makes it possible to pack the pixels into device-specific formats like RGB565.
