convert_image_array_to_mode(pixel_array, mode)

Convert an image ndarray to one of the built-in image modes.

Pillow performs the color/channel conversion. Bit-depth conversion between 16-bit and 8-bit modes uses the same linear scaling as Rust’s image crate: uint16 // 257 when reducing to 8-bit and uint8 * 257 when expanding to L16.
