Allow read access to the Work directory from JavaScript

As suggested by FlyingRaccoon, reposting my previous question as an idea so people can vote on this.

With the current version of the SDK, JavaScript can only read files in the package folder. It would be great to be able to read files in the work directory too. Allowing this would open up many possibilities for WASM modules to write a data to a file and have JavaScript consume it, without needing to send this data in tiny chunks over L-Vars.

I really don't think we want file-io as the preferred method of passing structured data in real-time between systems. Would the JS be polling the file to see if anything new is in there?

A basic implementation of event-driven async message passing (e.g. callbacks) would fit the JS model particularly well, i.e. the JS would register a callback that the WASM could trigger. Ideally this would be possible in both directions. If bridging JS and wasm/c++ structured data is too complex, the lowest common denominator would be an argument including a string payload, so similar to your file-io but without the polling.
