[bug]: Security issue due to outdated tsup

[kazazor]

Describe the bug

Since this repo still using tsup version 6.x.x there is a security issue with rollup. This issue was already resolved but there is a need to update to the latest version of tsup (8.x.x)

From what I saw the only breaking changes are the node versions so it will support version 18+.
Looking at the engines section of this repo it seems anyway it's intended to support only node 18+.

So I don't see a reason why not to update and resolve the security issue.

How to reproduce

You can start using dependabot security alarms in this repo and you'll see it for yourself.
I do not have a link to anything here as it's a security issue.
