<issue_title>[FEATURE] Lottie play certain frames</issue_title>
<issue_description>Be able to play to a certain frames. The lottie documentation has a goToAndStop

I'd like to create a switch using a lottie animation, but without this sort of functionality its impossible.

Comments on the Issue (you are @copilot in this section)

@mattleibow I think all of these actions can be performed using properties:

• IsAnimationEnabled - true is start and false is stop
• Progress - TimeSpan of the progress
• Duration - TimeSpan of the total time

If you want to get a percent progress then you can convert the Duration into TotalSeconds and then use that to get a percentage and convert back into a TimeSpan for the Progress property.</comment_new>

• Fixes [FEATURE] Lottie play certain frames #166
