updateFirmware.py does not convert between shields

[lbussy]

When using the --shield/-h switch to change shields, the script does not change between pin 14 and 18 so the import fails with:

ERROR 9: Device is onewire but pin 18 is not configured as a onewire bus.
ERROR 3: Device definition update specification is invalid.
