Added delete button and move up/down arrows

[EliseWindbloom]

Thank you for this amazing audiobook maker project and for sharing it with everyone. Also, apologies if this is the wrong place to put this, as i wasn't able to find the file in the repo and I am still a newbie to pull requests.

I've added a new delete button feature and up/down arrows to the Audiobook Maker GUI, via the audio_book_app.py file. Here are the new features:

-Press up arrow button to make the selected sentence move up one row, press down arrow button to make the selected sentence move down one row.
-Press the "DEL" button next to the sentence to delete that sentence.
-Press the "Show Delete" button to show/hide the "DEL" buttons to avoid accidentally deleting a sentence.
-The wav filenames/json will be updated in the background accordingly based on what you click on.

I've downloaded your release here and edited the audio_book_app.py within it to create the new features: https://huggingface.co/Jmica/audiobook_maker/blob/main/audiobook_maker_v3.0.zip

You may want to edit it to your liking more, but this updated file (the attached audio_book_app.py.txt. Remove ".txt" from filename to use) should completely work as-is by just using it with the v3.0 package.

I was going to make a pull request but i can't seem to find audio_book_app.py in the repo, outside of the Releases section. Again, sorry if i'm doing this incorrectly and thank you for the amazing project.

Hey Elise,

Thanks for the contribution, this is an older version of the ABM which is why you aren't able to find the file. I'll add this as a possible enhancement to add later into the maker though!

Nice, thanks for telling me and sounds cool. I just saw your new video update of Audiobook Maker, it's looking great! Wish you the best of luck.
