Wasm module doesn't work

[ghost]

In #3, it was covered that the Wasm module cannot be made useful in any way whatsoever.

In #3 (comment), I suggested stubbing everything, but it's no better than to not serve a file at all anyways.

If we want to stub anyways, here: coinhive-wasm.tar.gz, I could create a pull request merging a file that causes loading the module to trap - but again, it seems useless. Let's leave users to simply have HTTP errors upon requesting the wasm.
