[lyrics][FEATURE] Aligned lyrics

[lucaphill]

Submission checklist

• I have searched existing issues and confirmed this has not been requested before.
• I have checked existing pull requests for similar changes.
• This is about a community plugin, not about Noctalia itself (those belong in the noctalia repo).

UI / visual improvement

Feature summary

An option to center the lyrics within the size predefined by the plugin to improve visual consistency

Motivation / use case

I wanted to use the plugin as a separate, standalone bar, but right now it looks really odd because the characters don't have a fixed start and end position, they sort of adapt to the length of the phrase, so when the song lyrics are short, it doesn't align properly.

Proposed solution

Perhaps instead of just setting the number of characters to display, there could be an option to set a maximum size.
Then, you could add an option to align the lyrics to the right, left, or center based on that fixed size.
