[Feature/Improvement] Skip Intervals During a Workout

[Milchreis]

Purpose:
As a user, I want to skip to a specific interval by clicking on it, because I stopped the workout by swiping on the screen.

More details:
The workout / interval starts every time on the beginning. Sometimes I want to skip some parts. For me it would be perfect, to move to the part which I click on.

Acceptance Criteria:
Intervals are skipped by click on later interval.

BTW: it's a really nice app and works great, thank you 😊👍
