[BUG] Using <script type="module"> does not work since v1.0.5

[H-L]

Describe the bug
It seems that window.sharedworker is not defined by @okikio/sharedworker/lib/index.js anymore.
Console will return an error like : TypeError: Right side of assignement cannot be destructured.

I had the error on an "old" Safari 15.6 browser.

• Script is working correctly at v1.0.4 but breaks at v1.0.5 on this particular use case.
• It seems the way the script is compiled into /lib has changed, and does not have the necessary code to support older browser.

To Reproduce
Load the script using <script type="module"> tags exactly as described in the README:

<script src="https://unpkg.com/@okikio/sharedworker" type="module"></script>
<script type="module">
    // You can then use it like this
    const { SharedWorkerPolyfill: SharedWorker } = window.sharedworker; 
</script>

Console will return an error like : TypeError: Right side of assignement cannot be destructured.

Expected behavior
Loading the umd script as described in the docs works, and window.sharedworker is defined once @okikio/sharedworker/lib/index.js or https://unpkg.com/@okikio/sharedworker is loaded.

Only "Fix" I found comes from this tsup opened issue. It seems this bundler does not support umd yet, but there is a workaround using esbuild (used by tsup).

Thanks for bring the issue to my attention I'll draft a fix for it quickly

This should now be fixed, but please use <script src="https://unpkg.com/@okikio/sharedworker"></script> remove type module from the import, I'll have to update the docs sorry, for the inconvenience, here's a demo https://codepen.io/okikio/pen/qBvoygR?editors=1111

Thanks a lot for your quick reaction !

Just tried the v1.0.7 on the same Safari 15.6 and the bug is fixed, using the index.umd.js version.
