Is your feature request related to a problem? Please describe.

When using arm64 (Linux or mac M1) it would be nice to have a native binary and image that didn't run under emulation.

Also, ARM nodes on GKE are a thing, so it would be handy to be able to run on them too.

Describe the solution you'd like

• Publish an linux/arm64 binary.
• Make the quilkin release image multi-arch and have images for both linux/amd64 and linux/arm64 under the same name and tag.

Describe alternatives you've considered

Don't do it. But it would be handy, so let's do it. Also shouldn't be too hard, the docker image is pretty straight forward.

Additional context

• https://docs.docker.com/build/building/multi-platform/
• Should wait for Get build tooling working on ARM/M1 Mac #608 to get it's upcoming PR, since there is a lot of cross compilation work in there.
