The jscad worker code was hosted as a static asset, making it odd
javascript where we have to be conscious of what javascript features we
can use and if it will work on older browsers, plus it can't be
typescript like the rest of the codebase.
Since redwood 0.36 we using webpack 5 should make loading workers easy

But I had trouble with this (see:
https://community.redwoodjs.com/t/has-anyone-tried-workers-with-webpack-5-rw0-36-x/2394)
and instead used the webpack 4 loader without any issues
This issue relates to #411 , and is a checklist item on #444Resolves#494
