Export default parse rules, another version

[sawyerpollard]

Hello Benjamin Bray! Thank you for your work on this plugin. I see that another person made a pull request to export default parse rules, but I figured I'd make a slight tweak to that PR. This doesn't alter any imports unlike the other PR. This pull request simply exports the parse rules from index.ts and rebuilt the dist folder with npm run build:dist.

I think this would be a valuable feature, unless of course the implementation is considered too experimental.

Anyways, thank you for the work you do!
