Remove legacy conversion of modules
We no longer support Internet Explorer so we can now require that browsers support modules. Some conversion to commonjs still remains for nodejs.

Custom Browser ES Module Loader
|
||||
===============================
|
||||
|
||||
This is a module loader using babel and the ES Module Loader polyfill.
|
||||
It's based heavily on
|
||||
https://github.com/ModuleLoader/browser-es-module-loader, but uses
|
||||
WebWorkers to compile the modules in the background.
|
||||
|
||||
To generate, run `npx rollup -c` in this directory, and then run
|
||||
`./genworker.js`.
