remove cyclical dependencies

[ericwooley]

I'm trying to use this in a sveltkit project, which uses vite, which does not seem to handle the cyclical dependencies as well as some of the other build tools.

Because some of the files are importing things from '.', which pulls from index.ts, which exports all, there is a cyclical dependency.

I'm having other build issues, but this is the first error to get past.
