Problem description:

While calling STLExporter.parse the following uncaught exception is raised:

Uncaught TypeError: Cannot read properties of undefined (reading 'triangles')
    at STLExporter.js:65:1
    at Mesh.traverse (three.module.js:6983:1)
    at STLExporter.parse (STLExporter.js:55:1)
    at Object.save (SceneSetup.tsx:118:1)

Suggested solution:

The callback in https://github.com/pmndrs/three-stdlib/blob/main/src/exporters/STLExporter.ts#L55 should be an arrow function, so that this is correctly binded in https://github.com/pmndrs/three-stdlib/blob/main/src/exporters/STLExporter.ts#L66
