Interface DracoDecodeOptions

A ready draco3d decoder module, as createDecoderModule resolves. When omitted, one is created from the draco3d package and shared across calls. Pass one in to reuse a module (or to supply the .wasm in an environment the default lookup cannot reach, like a bundled Worker).

The decoder .wasm bytes, forwarded to createDecoderModule when the shared module is created. Bundlers cannot always locate draco3d's own .wasm next to its glue (Vite workers, inlined builds): fetch the decoder asset (a ?url import of draco3d/draco_decoder.wasm) and pass its bytes here. Ignored when decoderModule is given.
