feat: Implement Batch Scanning Support

[techwallahexplorer]

Resolves #1

This PR adds batch scanning functionality to nxc-scan, allowing users to define multiple sets of flags for sequential execution against the same target services.

Key changes:

• Added --batch-<protocol> arguments to support inline JSON or configuration file definitions for batched flags.
• Updated config.py to handle the new service_batches dictionary.
• Modified the main loop in nxc_scan.py to iterate through batch definitions and merge configuration seamlessly for each sweep.
• Preserved existing features such as the --output-file streaming functionality.

Please review and let me know if any adjustments are needed.

Tested it and it works as intended. See example below.
