Request for NPM release with Unicode 15 support

[Vizards]

Hi there,

I noticed that Unicode 15 support has been added to the codebase in several commits between eaf9df3 and e0960d3, which is fantastic work! However, I see that this functionality hasn't been released to npm yet, as there hasn't been a version bump in package.json.

Many downstream projects, including vercel/satori, would benefit greatly from having Unicode 15 line breaking support. This update is particularly important for proper text/emoji rendering in various languages and scenarios.

Is there anything blocking the release of these changes as a new version (perhaps v1.1.1)? If there are any open tasks or testing needed before publishing, I'd be happy to help however I can.

Thanks for maintaining this valuable project!
