`nearest_aligned` is not aligned about trainner HOT 2 OPEN

Any change in nearest_aligned would go in https://github.com/victorca25/augmennt, but can you test what I commented here:

For the cases I tested, the images were aligned, but maybe in some cases it needs a larger blur kernel.

I've tested it on multiple files, it's not like the input file matters. I first noticed it as warping in the output of my models, which was obviously apparent and corrected after I implemented my own local fix, but my local fix is a hack that can't be merged that only works locally because I don't trigger any other code paths that use sample().

As the code is now it's simply wrong. I cannot guess how you tested it to make it appear correct, but my tests are repeatable at both 2x and 4x.
