wasm path is not correct in electron environment

When use draco in my electron app, It fetch http://draco_encoder.wasm/

It's ok when I use it in my react useMount hooks, I can get table.wasm with code
It fetch http://localhost:8238/table.wasm

```
useMount(()=>{
var otherTable = new WebAssembly.Table({ element: "anyfunc", initial: 2 });

WebAssembly.instantiateStreaming(fetch('table.wasm',{credentials:"same-origin"}))
.then(obj => {
var tbl = obj.instance.exports.tbl as any;
console.log(tbl.get(0)()); // 13
console.log(tbl.get(1)()); // 42

otherTable.set(0,tbl.get(0));
otherTable.set(1,tbl.get(1));

console.log(otherTable.get(0)());
console.log(otherTable.get(1)());
});
})
```

But when I use gltf-pipeline, it depences on your draco, and ,it fetch http://draco_encoder.wasm/
And error is ` no such file or directory, open '\draco_encoder.wasm'`


how does draco change the base url?
