Scaffold for basic Aspect Workflows project

Create a new project from scratch on macos:

% brew install aspect-build/aspect/aspect
% aspect init

Note, it's also possible to run this outside of aspect init using scaffold like so:

% brew tap hay-kot/scaffold-tap
% brew install scaffold
% scaffold new https://github.com/aspect-build/aspect-workflows-template.git
