Implement a Data Persistence Worker

[proXDhiya]

We need to implement a worker will handle data persistence within our application. This worker should listen for a save signal, take a snapshot of the current application data, and save it to a file named dump.rdb by default in the same file path as the application.

Requirements:

• The worker should be able to:
  • Listen for a save signal within the application.
  • Capture a copy of the current application data.
  • Serialize the data according to the RDB (Redis Data Persistence) file format.
  • Save the serialized data to dump.rdb in the same file path as the application by default.

Acceptance Criteria:

• The worker listens for and correctly responds to the save signal.
• Data is accurately captured and serialized according to the RDB format.
• The serialized data is saved to a file named dump.rdb in the appropriate file path.
• The implementation is tested to ensure that the dump.rdb file can be used for data restoration.
• The file name should follow the arguments if set or uses dump.rdb

Additional Notes:

• Ensure the implementation follows best practices for worker design in BunJS.
• Consider edge cases where the save signal may be triggered multiple times in quick succession.
