Organize imports and add requirements.txt

This commit streamlines the import line in translate.py for better readability by putting List and Tuple from 'typing' on the same line. Additionally, a requirements.txt file has been created. This file lists all necessary packages to run the program, making it easier for other developers to know what libraries and versions need to be installed.
