[Feature] Hold button keep awake

[mitmarcus]

A new setting along side copy UID when you hold a button
Its a bit annoying when the chameleon goes sleep when you try to pair/connect by bluetooth

Why not increase the sleep time instead? I like the battery conservation of it going sleep as soon as possible and also it's only in specific usecases you need to connect to bluetooth.

I created #152 to expand the initial wake period from 4 to 8 seconds to help address pair/connect via bluetooth.

The change will only expand the first button press which wakes the device, subsequent button presses remain or reset to 4s
