ANTs release binaries

[cookpa]

Related to issue #802

I think I've made some progress on this in #1393 . I have a default Superbuild working on CentOS, Ubuntu, and Mac. I don't have any capability to do Windows, but happy to work with anyone who can help with that.

I'm interested in user feedback on what kinds of builds would be useful. Because of the time limitations of Github runners, building on other architectures than X64 is unlikely to be possible.

VTK support might be do-able, if there's interest.

Are there any other options we should consider?
