v0.1.4 and v0.1.6 fails to build for darwin arm64

[mdeggies]

The two latest releases (since the bash->go refactoring) fail to build darwin arm64 artifacts properly. Pinning to v0.1.3 (for darwin builds) is a current workaround for this issue. There are a lot of commits from v0.1.3 -> v0.1.6, so this has not been an easy one to troubleshoot or fix. I'm setting aside this aside for now, and will plan to reach out to @samsalisbury or @alvin-huang when they're back to troubleshoot further and provide a fix.
