[Feature]: Ability to further customize layout

[NickTheWilder]

Describe the solution you'd like I personally never use Albums & Artists in Spotify, only playlist to sort songs. It would be nice to be able to

1. Remove columns
2. Add different columns to replace them (seems more complicated but a nice to have)

Describe alternatives you've considered Adjusting the layout of playlists/albums in the config to potentially hide the columns

ℹ️ FWIW the layout settings don't work for me, Win11 - PowerShell v7.4.4 - scoop v0.19.1 Current settings:

# omitted other settings above
[layout]
library = { playlist_percent = 75, album_percent = 12 }
playback_window_position = "Top"

Additional context I'd start working on this if I had experience with Rust and open a PR but no experience here. Really enjoy what's going on so far.
