initial commit
rewrite in c
fully working with button
fully functioning including button and channel leds
enabled 3rd segment
trying to eliminate darker g segment
everything working

now PB0 is segment g + button and PB1-3 are segment driver because PB3 has 600k pullup instead of 38k which we need for our button stuff to work properly
detailed info about fusebits

lots of stuff done

adapted to wrong hardware layout
both channels 0-14.6V range
