xworker hooks cannot be used

[bugzpodder]

Users may need to be able to hook into XWorker runtime.

I've tried to pass in functions to onAfterRun/onAfterRunAsync and got an error.

This may repro: https://bugzpodder.pyscriptapps.com/polyscript-worker-errors-copy/latest/
However the domain is blocked by my computer so I don't know exactly.

Not sure if its webpack specific or not but it seems that the error is just serializing a function to postMessage which doesnt work, makes sense.

As the TypeScript hints, and documentation should tell too, anything Worker related has to be a string. You can't pass functions because you can't pass the main scope down to workers ... this is a Web limitation, not a polyscript one, I am afraid.

P.S. please feel free to check PyScript next branch, pyscript.core folder, to see how we use worker hooks to bootstrap the module within Workers.
