Add new scripts to package.json and handle rpm/rph conflict

Updated the package.json with two new scripts: copy-local and build-local. This allows for easier local testing by building and copying the program to a local directory. In index.js, handled the situation where both rpm and rph options are provided by the user, which was causing conflicts. This is resolved by adding explicit handling which returns an error and asks the user to choose only one.
