An in-range update of tape is breaking the build 🚨

Version 4.7.0 of tape just got published.

Branch Build failing 🚨
Dependency tape
Current Version 4.6.3
Type devDependency

This version is covered by your current version range and after updating it in your project the build failed.

As tape is “only” a devDependency of this project it might not break production or downstream projects, but “only” your build or test tools – preventing new deploys or publishes.

I recommend you give this issue a high priority. I’m sure you can resolve this 💪

Action Required: Fix Renovate Configuration

There is an error with this repository's Renovate configuration that needs to be fixed. As a precaution, Renovate will stop PRs until it is resolved.

Error type: undefined. Note: this is a nested preset so please contact the preset author if you are unable to fix it yourself.

Improved Parsing

Hello,

Could I create a PR for an improved version of the parser? When trying to parse something like this chemFormula('HOCH2(CH2)2OH') the current version of the script doesn't work as expected.

I'd love to give this a shot; let me know what you think.

Thanks
