Interrupt signal from optional VL53L0X

1. These interrupt signals are duplicated, but not used by default, this offers hardware connection of the

satellite board VL53L0X interrupt signals and flexibility in case of conflict on MCU interface management

when expansion board is used superposed with other expansion boards. In this case select, through a

solder drop, the MCU port which is free.
