Currently playing item customization

[Rarataxy]

There are the highlighted_item_style and current_item_style theme properties which allow for changing the color and font style of the currently playing song/ hovered item.

I think it would be a worthwhile change to allow for customizing the item itself by adding text or symbols to it, akin to how we define it's appearance in the first place; allowing for features like showing the duration for the currently hovered over song only or preserving colors when multiple are used in the queue ( artist[red] - title[blue] ).

Visual explanation just in case:

Feint - Drifters
♪ Feint - Solace               (playing)
Feint - Snake Eyes

Feint - Drifters
Feint - Solace                 4:28  (hovered)
Feint - Snake Eyes

Edit: Idk why it didn't work before, but colors do get preserved when explicitly set

I would not mind this, but there are some limitations to what can be done. The whole thing is a table, meaning the currently playing song row has to respect the column count/sizes of the table as whole.

Then there is a question of how should this interact between the highlighted_item_style and current_item_style? Maybe ignore the current_item_style style entirely if set and use highlighted_item_style for the style but keep the custom format?

Anyway, it looks like the next version of ratatui will allow cells to span multiple columns so this would be possible ratatui/ratatui#2150.

Other than this, it should be fairly simple to implement, so waiting for the new ratatui version is probably for the best atm.
