Add IFCBRIDGE to IfcImporter default elements

[ynnob]

Description 📝

The WEBIFC.IFCBRIDGE is currently missing as an default element in classes.ts
I suggest adding it to be added as a default element. WEBIFC.BRIDGEPART elements for example might be children of WEBIFC.IFCBRIDGE and could be ignored without that element beeing processed.

Suggested solution 💡

Add WEBIFC.IFCBRIDGE

Alternative ⛕

Manually add WEBIFC.IFCBRIDGE to serializer.classes.elements

example:

  const serializer = new FRAGS.IfcImporter();
  const webIfcVersion = `webifc_${webIfcPkg.version}`;

  serializer.wasm = {
    path: `./wasm/${webIfcVersion}/`,
    absolute: false,
  };

  // missing in packages/fragments/src/Importers/IfcImporter/src/classes.ts
  serializer.classes.elements.add(WEBIFC.IFCBRIDGE);

Additional context ☝️

Missing this element can cause an entire tree structure to be incomplete. For example Viadotto Acerno

This Bridge has IFCBRIDGEPART elements as children of IFCBRIDGE but since IFCBRIDGE is not included as default they will not be visible/processed.
