Enhance generate_mp3.sh script

- Add 'weather' to category_order array to include weather information in the generated MP3 files.
- Create directories /sdcard/.mp3/ and /sdcard/.text/ to store MP3 and text files respectively.
- Update txt_dir and mp3_dir paths to use /sdcard/ instead of /data/scripts/.
- Modify the 'am start' command to open handout.html in a Chromium tabbed activity for better compatibility.
- Remove unnecessary commented-out am start command and replace it with an updated command.
- Improve comments for better script understanding.
