Pyraf

Major changes are

* pyobjc is now a required package on macOS and aqutil is updated to use Cocoa instead of Carbon,
* scanf is implemented in Python, so PyRAF is pure Python on macOS. On Linux, it still builds the xutil extension.

This is the release candidate for version 2.2.1.

This is the first PyRAF version maintained by the [iraf-community](https://iraf-community.github.io) organization, which is a community effort to keep IRAF available after the end of NOAO and STScI support. Consider contributing by reporting bugs, fixing them, or improving the software!

This version drops Python 2 support and applies many bug fixes, modernizations and other improvements. The code cache support for Python 3 is fixed, resulting in a huge speed improvement.
