Support decoding Image from a streaming data source

[colinrtwhite]

Hi, I was wondering if it's possible to support streaming image data when decoding an Image. At the moment it looks like Image only has methods to decode the image when its data is already all in memory (e.g. ByteArray, Pixmap). This requires consumers to buffer the entire image data into memory before decoding, which isn't ideal for performance.

I'd be nice to support an InputStream-like primitive (can be a custom type) so that users can decode Images without totally reading them into memory first. This would be especially useful for decoding from Files.

It looks Skia already has support for streams that could hopefully be leveraged. Thanks for the great library!

I guess this will land with kotlinx-io support as base or extensions?
