dnt Build Issues

Hopefully I am missing something simple. We have the dnt builds working in other libraries, but for some reason I can't get it to work in our new icons library: https://github.com/fathym-deno/atomic-icons

We have defined our dnt build in the `./scripts/npm.build.ts` file, but we are getting the following error:

```
[dnt] Top level await cannot be used when distributing CommonJS/UMD (See deps/deno.land/x/fresh@1.3.1/src/server/build_id.ts 6:21). Please re-organize your code to not use a top level await or only distribute an ES module by setting the 'scriptModule' build option to false.
error: Uncaught (in promise) Error: Build failed due to top level await when creating CommonJS/UMD package.
throw new Error(

```

Based on the error, it appears as though it is trying to treat `npm.build.ts` as the entrypoint. What am i missing in this project to get it to work?
