Simple download and run the example locally does not work( on Windows 10)

I have clonned your repository hoping that I can run the https://github.com/3box/sss-wasm/tree/master/example offline from my system, the index opens, but the logic does not work.
Browser console shows loading errors like `Fetch API cannot load file:///C:/Users/myUser/Desktop/sss-wasm-master/example/wrapper.wasm. URL scheme must be "http" or "https" for CORS request.` Further there is this trace:

```
sss-wasm.js:13463 wasm streaming compile failed: TypeError: Failed to fetch

```
There is a few more and the last is `Uncaught (in promise) abort("abort(\"on the web, we need the wasm binary to be preloaded and set on Module['wasmBinary']. emcc.py will do that for you when generating HTML (but not JS)\"). Build with -s ASSERTIONS=1 for more info."). Build with -s ASSERTIONS=1 for more info.`
