WASM support

[jpochyla]

Hello, I was wondering whether you see ofx-parallel supporting parallelism with wasm-bindgen, the way https://github.com/GoogleChromeLabs/wasm-bindgen-rayon is doing it: pre-spawning fixed number of worker threads (through web workers) and building the thread pool from them.

Hi @jpochyla .

Thanks a lot for the suggestion. I received a similar suggestion for using thread pools; although with a different objective, in order to reduce spawning overhead with many small parallel computations.

Created issue #82 to enable this and will start working on it shortly.

I hope we can also use this parallel runner for wasm. Once, the issue is fixed, we can look into this.

Please let me know if you have comments on this or have different suggestions.
