 Getting close to the final version of external ROM switcher for support for 8KiB or 16KiB banks. Changes from 1.1 to the board:
 - Making PADS 2mm longer, to prevent potential issues with some connectors (when used in the Expander board)
 - Changed from pull-ups to pull-downs, to match actual behaviour of DIP-SWITCH (up = 1/ON/HIGH, down = 0/OFF/LOW)
