fix: improve checking for Rez (fix #994) (#995)

* fix: improve checking for Rez (fix #994)

Check for Rez in Xcode.app and in command line tools, and error if neither is installed.

* Remove hardcoded paths in favor of xcode-select --print-path

This reverts commit 54784a0.

I'm not sure that this string substition will work how I want it to.

* Finally...fix issue finding xcode-select tools

* Add tip asking to run xcode-select --install

* Trim tailing whitespace

* add changefile
