idle timeout

[aki-akaguma]

The webworker in the pool remains forever. I want it to disappear with an idle timeout.

Interesting idea, I'll have a look into how/whether this could be achieved later today! Thanks for opening an issue!

Fully implemented and will be part of an intermediate release that I'll do basically now.
Changes are part of https://github.com/paberr/wasmworker/releases/tag/v0.3.0
