[FEAT] Allow Skipping to the next period

[damascene]

This app seems awesome. I miss one feature to allow me to skip the current running timer to the next period.

Like skip running Work time >> Relax time or skip Relax time to work time
It's useful if you start the application in the middle of working period and you want to synchronize your time when you finish.

Thank you for creating an issue. I'll take a look soon as I can.

It might be better to just add a shortcut for this than a Text-UI button. 👍🏽
