New board:

1. PCB outline to match hw_48_na and 64 pin connector location to match https://github.com/rusefi/rusefi/tree/master/hardware/frankenso

1.5) hw_48_na outline is an improved frankenso. While older frankenso has proper 64 pin header location, newew hw_48_na has minor shape corrections.

2. Same pinout on 22 and 26 sections as https://github.com/rusefi/hw_48_na same jumpers to switch between https://github.com/rusefi/rusefi/wiki/Mazda-Miata-1990 and https://github.com/rusefi/rusefi/wiki/Mazda-Miata-1994 vehicles

3. Middle 16 pin plug to become https://github.com/mck1117/wideband Hellen-style module

This brings us to "make https://github.com/mck1117/wideband Hellen-style module" subtask:

1. start from https://github.com/mck1117/wideband/tree/master/board_module

2. add TBD SWD header
