Relative path in noroutine.js

[Wansmer]

Describe the bug In file 'noroutine.js' on line 102 path for './lib/worker.js' is relative. This leads to error: trying find this file in working directory instead of package folder.

Example:

node:internal/event_target:646
  process.nextTick(() => { throw err; });
                           ^
Error: Cannot find module '/Users/wansmer/projects/code/noroutine-sh/lib/worker.js'
