Circular dependencies

[jacksonrr3]

Hello!

I am trying to create a bundle with rollup bundler using rrule and get this warning:
(!) Circular dependencies node_modules\rrule\dist\esm\src\index.js -> node_modules\rrule\dist\esm\src\rrule.js -> node_modules\rrule\dist\esm\src\nlp\index.js -> node_modules\rrule\dist\esm\src\nlp\totext.js -> node_modules\rrule\dist\esm\src\index.js node_modules\rrule\dist\esm\src\index.js -> node_modules\rrule\dist\esm\src\rrule.js -> node_modules\rrule\dist\esm\src\nlp\index.js -> node_modules\rrule\dist\esm\src\nlp\parsetext.js -> node_modules\rrule\dist\esm\src\index.js node_modules\rrule\dist\esm\src\index.js -> node_modules\rrule\dist\esm\src\rrule.js -> node_modules\rrule\dist\esm\src\nlp\index.js -> node_modules\rrule\dist\esm\src\index.js ...and 11 more

Steps to reproduce:

1. Download test project
2. run npm i
3. run npm run build

I believe my PR #465 resolves this. Can you try it out locally with the changes? I faced a similar problem as well.
