✨ Support reading multi-band GeoTIFF files

[weiji14]

Count the number of bands or channels in the GeoTIFF file when decoding by looking at ColorType.

Note that this relies on a patch to image-tiff that has been submitted as a pull request at image-rs/image-tiff#224

TODO:

• Initial implementation and unit test
• Add more unit tests on Python side
• Refactor once Add ColorType::Multiband enum variant to support samples>1 per pixel image-rs/image-tiff#224 is merged
• Improve error messaging
