More pin suport for Atmega328PB

[Fanotec]

Atmega328PB is very close to Atmega328. Can you add support for other pins.
ATmega88/168/328 (Uno, Nano, Pro) Supported pins: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, A0, A1
ATmega328PB Supported pins: 10

Ciao @Fanotec yes, it would be cool to expand Atmega328PB pin support, I will give it a try as soon as possible
