hey! Im pretty newbie in rust. Just finished extracting voxel position and it's all works, but how to extract rgba data for each voxel? Thanks!

Thanks for github, found here how to do this properly https://github.com/expenses/isomagic/blob/7f84772085d3f980e5766e5a8f5a33c85f50f5af/src/main.rs

    fn colour(&self, index: u8, subtract: u8) -> Rgba<u8> {
        let colour = self.palette[index as usize - 1];
        let r = (colour % 256) as u8;
        let g = ((colour >> 8)  % 256) as u8;
        let b = ((colour >> 16) % 256) as u8;
        let a = ((colour >> 24) % 256) as u8;

        let r = r.saturating_sub(subtract);
        let g = g.saturating_sub(subtract);
        let b = b.saturating_sub(subtract);

        Rgba {
            data: [r, g, b, a]
        }
    }
