Add automatic whiptail installation and error notices for missing software dependencies #8

This commit modifies the script to automatically install 'whiptail' on Linux, macOS, and Windows if it's not already installed. It also adds error notices instructing the user to install other software dependencies if they're missing. This makes the script more user-friendly and reduces the likelihood of script failure due to missing dependencies.
