Esprima minification results in out of memory error on upload

@Wilberforce it is merged, it's just not live yet - you should be able to load it manually from GitHub if you want to try it. Before putting it live I want to test the module loading on the main IDE platforms first.

In this case it sounds like Terser is unlikely to help (if the issue really is that everything gets shoved on one line).

I'd suggest turning on Direct to Flash as Wilberforce suggests. That will automatically split code, but also has the bonus that any function code will be executed direct from flash, saving you a bunch of memory.
