Initial commit

Added generate_mp3.sh script:
- Author: Michael Haider
- Created on: 26.01.2024
- Description: This script generates MP3 files from text files in German and Spanish using gtts-cli (Google Text-to-Speech).
- The script exports the path to the programs, defines language and category order, sets directories, and includes a function to create MP3 files.
- The generated MP3 files are created with gtts-cli in German or Spanish slow mode based on the file content.
- The script then sets the media volume and loops through categories and languages to play the generated MP3 files at normal or half speed, based on the language indication.
