Try to fix #875 . Still a draft and a lot to discuss and finish.

Handle the tag: NO_DATA, use NO_DATA value to full fill the padded part of tile, or just make the padded part transparent
Scaling raw values from non-8-bit images
Should we make the output file format of get_tile of COG a configuration, currently the pixels read from COG tile will be transform to a png without alpha channel, but I think an with alpha channel would be better?
Others .. Will be added later.
