Reduce docker/podman image size

[notmandatory]

Need to figure out why the image for nonce_guess is so large (694 MB). We don't need SSL so maybe there's some features we can disable for tokio and/or other dependencies. Also could possibly use slimmer base image for the final image.

podman image ls
