Refreshing my previous attempt at packaging ANTs 🤞

Checklist

• Title of this PR is meaningful: e.g. "Adding my_nifty_package", not "updated meta.yaml".
• License file is packaged (see here for an example).
• Source is from official source.
• Package does not vendor other packages. (If a package uses the source of another package, they should be separate packages or the licenses of all packages need to be packaged).
• Package does not ship static libraries. If static libraries are needed, follow CFEP-18.
• Build number is 0.
• A tarball (url) rather than a repo (e.g. git_url) is used in your recipe (see here for more details). ANTs prefers building from Git rather than tarballs for encoding its version.
• GitHub users listed in the maintainer section have posted a comment confirming they are willing to be listed there.
• When in trouble, please check our knowledge base documentation before pinging a team.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipes/ants) and found it was in an excellent condition.

Windows builds are failing, forwarded upstream. Not a big deal for an initial release.

@conda-forge/help-c-cpp This package is ready for review 🙏

Yo, look what I've found. Thanks for the effort, I was looking for ANTs recipe as well. I'm not conda-forge team, but I think you might want to @conda-forge/staged-recipes for reviewing.
