[Question] Can we add `lib/LessParser.js` in package.json exports list

[phoenisx]

This issue isn't about any errors, thus am not including the issue template details.

Can we add lib/LessParser.js and other internal modules to package.json -> exports property.
This will enable developers to extend postcss-less parser or tokenizer as desired.

postcss already exports all its internal modules, and I have also raised a PR in postcss-scss for the same: issue details here -> postcss/postcss-scss#140

Let me know if this is possible. Happy to raise a PR for the same, if approved 👍🏽
Thanks for all your efforts in this library 🎉
