Add get_pin to bounce object

[kingjin94]

Make pin that Bounce is attached to publicly accessible

Hi, why do you need to retrieve the pin number?

I need it too.
Saves 1B of RAM when you have to access pin number after Bounce is initialized.
I have to use :

class BounceExt: public Bounce
{
  public:
    uint8_t get_pin() {
      return pin;
    }
};

right now.
