130 webworker CreateIfcGuidToExpressIdMapping support

[longbiaochen]

Summary

• Added CreateIfcGuidToExpressIdMapping to the web-ifc worker API surface.
• Wired the action through WorkerActions, WebIfcHandler, and WebIfcWorker.
• Added typing to WebIfcAPI so ifcLoader.ifcManager.ifcAPI.CreateIfcGuidToExpressIdMapping(...) works in both direct and worker mode.

Validation

• npx tsc -p config/tsconfig.json --noEmit ✅
• npm run build ❌ (environment issue: rollup-plugin-typescript2 fails on tslib package.json exports in current workspace)

Fixes #130

@agviegas quick ping on PR #198: this adds WebWorker support for issue #130 and keeps changes under 50 lines. If you can give a quick pass/any blocker notes, I can address immediately.

Final ping @agviegas: I only need a 1-line first-pass status (accept / needs adjustment / please close). If needed I can change in a single follow-up commit within 30 min.

Hi @longbiaochen

We have officially released the new library components on September 20 2023. This library substitutes web-ifc-three and web-ifc-viewer. Both WIV and WIT will remain up, but they will be deprecated and won't be maintained any longer. You are free to fork this if you want to maintain it yourself. You can find the new docs here.

All our efforts are going towards components now. The API is very similar, so I strongly suggest you make the leap and start using it. If you still face this issue with it, you can open an issue there and we'll take a look.
