cli-v0.4.3

• Added missing import: fileURLToPath from url.
• At the same time adding imports that are used but not yet imported: os and execFileSync.
• Fixed the flow of getOrDownloadTemplate(...) results that return object:
  • from const templatePath = ...
  • so const { templatePath, cleanup } = ...
• Fixed cleanup callback:
  • from cleanupTemplate?.()
  • so cleanup?.()
