Restore node_modules only if package-lock.json has changed before previous restoration.

npx ci-once

npm install -g npm-ci-once

And then use:

npm-ci-once

See the tiny implementation: src/main.js.

• Restoration: To restore, this script spawns a default shell to execute npm ci.
• Skipping unnecessary restoration: After restoration, this script writes SHA-256 hash value of package-lock.json to a file under node_modules. This scripts also checks if the hash value has changed or not.
