Vec3 typescript type removed in 18.1.2

[demedos]

Hello,

It seems that since version 18.1.2, the Vec* types are no longer exported from the Matrix4 file. This change should likely be noted as a breaking change, as it may cause issues with builds that rely on these types.

Here's the relevant pull request: #519

Thank you for your awesome work!

Would you like me to re-export these? 🤔

That would be great; I'm implementing something similar to what you've done with the sticker app a few years back here, and re-exporting these types would help maintain backward compatibility
