Add a pull up Option for physical Control

[TimPGamer]

Is your feature request related to a problem? Please describe.
I cant use timelapse, as it isnt implemented (yet), so i‘d Like to use the Pins with a Timer to trigger the cam in a certain timed way. So physical Control. Sadly i can only make it so, that the Line goes high and not low.

Describe the solution you'd like
At the bottom or top of the pin selection a Little dropdown with the Option of selecting pull up or pull down.

Describe alternatives you've considered
Maybe a Little extra Tutorial in the Readme, to Tell the ppl, how to get around it, by changing the Code, Like i did, by Adding „, pull_up = False“.

Additional context
I also had to get out the GPIOzero docs to Figuren out how the Button works. So maybe in the Future an explanaition would be nice. Also all of this Applies to the LED, just with the difference that ist Named „active_high“.

Tutorial for others
To change the Button pull_up, Go to App.py and Insert „, pull_up = False“ in line 200 After or before „, bounce_time = 0.1“.
