`pdf-lib` depends on a broken version of tslib

[avalero]

What were you trying to do?

Trying to use pdf-lib on Deno 2.4

How did you attempt to do it?

it produces this error

index.js:3 Uncaught TypeError: Cannot destructure property '__extends' of 'import_tslib.default' as it is undefined.
    at index.js:3:5
(anonymous)    @    index.js:3

This error throws just Just with const mergedPdf = await PDFDocument.create();

What actually happened?

pdf-lib depends on a broken version of tslib. The version it depends on is not valid ESM and a mix of CJS + UMD instead. This avoid using pdf-lib with Deno. Could you update tslib dependency

What did you expect to happen?

It should not throw any error :)

How can we reproduce the issue?

Try this on Deno 2.4

import {PDFDocument} from "npm:pdf-lib"
const mergedPdf = await PDFDocument.create();

Version

1.17.1

What environment are you running pdf-lib in?

Deno
