New Action: Capture a Screenshot

[vibhor1102]

Exactly as title implies — capture a screenshot during execution and save it.
Could be ideal for niche cases of capturing an image to flex their scores/achievements, or for long-running or unsupervised scenarios to allow screenshot capture at specific points to capture a screenshot to debug later.

The images could by default go to downloads/Klick'r folder within android's pictures folder. With an option (specific to the action) to change it to a custom location, picked by them via file explorer.

Caveats:

• Klick'r might need to prompt users to allow access to files on device.
