Release non-wheel binaries for pip-free installation

[gjoseph92]

Perhaps a niche use-case, but sometimes I find myself SSHing into a box (say, a k8s node) that's running Python workloads in docker, but doesn't have pip installed on the bare VM. I'd love to just be able to curl a py-spy binary from GitHub releases for quick debugging.

Right now you can download a wheel, unzip it, and pull out the binary from .data, but having a link directly to the binary would be more convenient.
