alphaTab cannot be used directly via jsdelivr CDN anymore (ESM)

[Danielku15]

Is there an existing issue for this?

Current Behavior

When importing alphaTab directly from a CDN like JsDelivr (using ESM imports) we get a bunch of CORS errors when spawning the worker.

[AlphaTab][Rendering] Failed to create WebWorker: SecurityError: Failed to construct 'Worker': Script at 'https://cdn.jsdelivr.net/npm/@coderline/alphatab@latest/dist/alphaTab.worker.min.mjs' cannot be accessed from origin 'http://localhost:3000'.

Expected Behavior

The alphaTab worker and audio worklets (if possible) should launch via the ESM version allowing alphaTab to be used directly via CDNs.
