use bit operations to lightup bit counter diodes #2

I fiddled around with the bitcounter example and found an approach that is easily extensible for 3 or more bits, by checking for single bits in the current sum to lightup the according diode.

Thank you for the contribution!

Sorry for not getting back to you sooner, I've been busy. I've been meaning to review this, but I just haven't gotten to it yet. I will look at this tonight.
