feat: Add support for including specific columns in audit report

- Implemented the `-i` flag to specify columns to include in the audit report
- Now, users can choose to include selected columns like Module, Title, and Severity by using the `-i` option
- Example usage: `better-npm-audit audit -i Module,Title,Severity`
