Suggestion: Support for Different Delimiters

[walid1508]

The current script reads CSV files using a comma (,) as the default delimiter. I propose adding the ability to specify different delimiters (e.g., tab, semicolon) via a command-line argument or a configuration file.

Implementation Details:

• Add a command-line argument to specify the delimiter (e.g., npm start YourFileName --delimiter=;).
• Modify the readCSV function to use this delimiter when processing CSV files.
• Update the documentation to explain how to use this new feature.

I would be happy to contribute to this enhancement and submit a PR if this proposal is accepted. Thank you in advance for your consideration.
