Update logging and add file detection for calendar files

- Updated setup_logging function to accept a logfile argument with default value "log"
- Changed basicConfig to use the provided logfile argument
- Updated parse_args to set default logfile value to "log" in current directory
- Added while loop to detect calendar files in sync location before proceeding with main logic
- Updated main function to call setup_logging with args.logfile and added file detection logic
