feat: Add Swipe Support - Add multi-touch Swipe support

[pixel-shock]

Hi @sds100 ,

• as said, I've added multi-touch swipe support for the "swipe" action.
• I've also added the radio buttons for the user to choose between start and end coordiates and removed the double "select screenshot" button
• I've added some documentation to the function with triggers the multitouch.
• At the screenshot you can see what this code basically does (here from start top left to end bottom right)
  • the red dots are the original start and end points
  • the blue lines are the perpendicular lines
  • the green dots are the final virtual fingers based on the finger-count setup in the action itself
  • the green lines are the final swipe lines for each finger

And here is a simulator screenshot vor a 3-finger-swipe from top right to bottom left:

Sorry @sds100 to bother you with that, but did you had any time to have a look at this one? If you like it and merge it, is there any chance to trigger a new build and relase (to play store etc.)?

Cheers & THANK YOU Tino

Hi, it's still on my to-do list to review this 😄

Alright 😄 ... I know ... as a Dev it's hard to do such things after work ... same for me ... it's always tricky to get time slot for private stuff
