Changed to using scripts for polykeyWorker.js

[CMCDragonkai]

Description

According to @tegefaulkes this is the correct way of setting polykeyWorker.js. I've made the change here. Can you check if windows/linux builds work? If so, merge this PR.

[tegefaulkes]

Runs fine in WSL. But I think a change in the master is messing up the .exe.
Level is failing to create the database file since the path is invalid. I think you changed the path for that to use /tmp/ at some point?

[tegefaulkes]

Yeah, That absolute path is not valid in windows.

- const dir = argv[2] ?? '.';
+  const dir = argv[2] ?? '/tmp';
  await testLevel(dir);

Otherwise this PR is fine. @CMCDragonkai

[CMCDragonkai]

Yea I forgot about that. Instead of using /tmp. Use https://nodejs.org/api/os.html#os_os_tmpdir instead. Please make the change and merge.

On it.
