Yubikey support for age

Hi all, for those who use already modern age or rage (the Rust version) instead of GnuPG, there is now a plug-in available, which allows you to store your age secret key on a Yubikey. https://github.com/str4d/age-plugin-yubikey I tested it with age first, but age currently does not support it and will have it in the next version. It already works fine with rage. Regards Stefan
