Ability to specify worker_threads/tinyworker

Hello, I hope you are having a nice day (Stay safe!)

Would it be possible to make a pre-launch option where you could specify the method of spawning (but only for certain workers/pools ?)
Apparently, some modules like the canvas module are **not context aware** and therefore its impossible for me to use worker_threads... But then again I don't want to use child_processes for all pools/workers. Can *spawning a certain pool using tinyworker without touching the other pools* be possible without major changes?

PS: I'm on node12 but I had to make tweaks to force threads.js to use tiny-worker module but then again, all my stuff are now using child processes and consuming A LOT of resources.

If you have another advice I should use to combat the "non context aware" issue, I would love to hear it. Thanks a lot once again :D
