Support for Carbon MacBook (ARM64)

I've already made it work locally, it just requires this change to package.json: "cpu": [ "x64", "arm64" ]

And uploading the arm64 binary to your S3 bucket. As there's no way to include the binary in a PR I thought I'd open this issue instead. I've checked in the binary to my fork, so you can download it there if you like.
