Updating logic, simplifying requirements, and adding shuffle all

[johnpacheco1]

First, I just wanted to thank you @simonsickle for creating this! I recently got a tesla and have been annoyed by Tidal's lack of a shuffle feature. I was going to attempt to write a similar program to what you have created when I happened on this!

Changes:

README.md

• Added docs for ElectricShuffleAll.py

requirements.txt

• Some of the packages were causing issues with installation so I pared it down to only what is necessary

ElectricShuffle.py

• Changed logic to accommodate selecting from no shuffled playlists only
  • Made it so script does not print out playlists named "- Electrified"
  • Shuffling a playlist always deletes and creates a new "- Electrified" playlist
• Delete now actually deletes the shuffled playlist

**ElectricShuffleAll.py"

• Includes logic for using refresh token to auto-refresh token on run
  • As long as it is run at least once every week you won't have to re-login
• Iterates over and shuffles all playlists

This is awesome! One small request if you don't mind, though!

For maintainability and code quality, could you make the code copied to the "all" script shared (maybe through a module and classes).

That's a pretty big ask, so if you don't feel like taking that on let me know and I'll add a TODO for me to revisit in the future.

Thanks for the contribution

I will give it a shot!
