nix-build -A token-metadata-creator

when I run the build command, I encounter the following errors. could you provide a pre-built binary package for the Mac M1 platform? thanks :

```shell
http_proxy=http://127.0.0.1:7890 https_proxy=http://127.0.0.1:7890 nix-build -A token-metadata-creator
```

error:
