Feature request: Reset pressed time.

[JotarOne]

I have a case where I am using two buttons.
I am using "pressedFor" to trigger long press and if i press both buttons I can get an "extra" long press function.
My issue is that when i release one of the buttons, the other one triggers my "single button long press".
A function to reset the pressed time of the "other" button would force the "other" button to wait the whole allotted time again before pressedFor returns true.

Example:

void EasyButtonBase::resetTime()
{
	_last_change = millis();
} 

Thanks for a good, usable library!
