nodejs test doesn't work

If I put :

`var test = new this.libwasmaudio.Test();
`
Here :
https://github.com/madChopsCoderAu/WASMAudio/blob/4976a53e36b58ee9d0d1552206302f096d05fb39/test/RunTest.js#L33-L35

Then I get the issue that this.labwasmaudio.Test isn't defined.

The same code is tested working in the webApp/browser.

Looking for help on what to do to get it working in nodejs.
