Feature request: set the idle-timer timeout value

[SimoneMSR]

``I would like to use the library to set a specific timeout for the idle-timer. Would this be interesting?
This could be used also for turning the screen on and off.

I would like to do like this

import IdleTimerManager from 'react-native-idle-timer';

.....
function myHandler()[
  IdleTimerManager.setIdleTimeout(10*1000)
}
