Option to display timestamps (if available)

[VsevolodGolovanov]

Hi.

Would be great if there was an option to display timestamps along with the lyrics. I want that because the tracks I listen to often have sparse irregular lyrics, where lyrics "bursts" can be separated by minutes of instrumentals. As is, a simple flat list of phrases conveys a false sense of linear uniformity. I guess an option to spread the verses out accordingly could also be interesting. But timestamps are more useful.

Thanks for the great plugin!
