It is somehow slower than synckit and can be faster

I'm developing a similar util module inspired by this package and esbuild.

It is mainly using the structure from esbuild now with MessageChannel, and I run a benchmark https://github.com/rx-ts/synckit/blob/main/benchmarks/benchmark.txt, it seems much slower during runtime. I was thinking sync-threads would be much faster because it's using v8 serialization inside.

Maybe there are a few reasons:

1. synckit creates the worker in top createSyncFn and reuse it every time, that's why the load time is much slower that sync-threads
2. synckit use cache to speed up same file (not benchmarked)
3. Maybe the serialization has been improved without v8 (not confirmed, I'm not familiar with v8)

Hi @JounQin, you are right, this package can be made much faster and I made a PR for it : #3
