Tested on Apple M1 and AWS Graviton.
+ Add support for multiple-architecture building
+ Support for amd64, ppc64le and arm64v8 added
+ amd64 and arm64v8 will be automatically built by the CI
~ Major CI Overhauls
~ Added composite actions for the Docker build and setting environment variables
~ pdk build is now its own job, and amd64/aarch64 have a job each
~ matrix -> design_matrix, designs only tested on amd64 for performance reasons
~ run/build base docker images now pushed to Docker Hub based on a hash of dependency lists (to work with the buildx `docker-container` driver)
- Remove pandas (overkill for what we're using it for)
- Remove `cugr`, `drcu` *for now* (they're x86-64 Linux-only utilities)
