Pillow 10.0.0 deprecates Image.ANTIALIAS in util/artresizer.py

[arrrgi]

I noted that according to https://pillow.readthedocs.io/en/stable/releasenotes/10.0.0.html#constants the artresizer function will fail as the Image.ANTIALIAS constant has been deprecated.

Line 356 in a4e61e8

im.thumbnail(size, Image.ANTIALIAS)

Looking at the code above, it should probably be updated to use the new Image.LANCZOS or Image.Resampling.LANCZOS constant instead.

I'm not sure if this is backwards compatible into Pillow 9.5.0 but wanted to make the community aware of this breaking change.
