SDD engineer code generator

Generate SDD engineer passwords for functions such as CCF editing.

It only needs to know the seed and the type (Jaguar/Landrover) in order to generate the password for CCF editing. However it's advised to always provide --vin with --seed to ensure the seed matches the target vehicle to prevent incorrect passwords being generated.

If you don't provide a VIN it will output the last 6 digits of the VIN that it derives from the seed so you can double check it against the vehicle VIN to make sure it matches.

There maybe a security lockout by SDD or the ECU if you send it too many incorrect passwords - this is a presumption and has not been tested, don't blame me if you lockup your modules because you didn't check the seed matched the VIN.

Arguments

Argument	Description
-v / --vin <VIN>	VIN of the target vehicle
-s / --seed <seed>	SDD seed of the target vehicle
-g / --gen	Generate a seed for the provided VIN - will override --seed. This option probably isn't very useful in real life, it's mostly used for testing this code
-t / --type <JAG ¦ LR>	Manually set vehicle type to Jaguar (JAG) or Landrover (LR) instead of trying work it out from the VIN (overrides VIN if VIN is provided)
-o / --option <option>	SDD access option, it will default to CCF_EDITOR if this isn't provided

It's mandatory to provide at least one of these combinations:

--seed and --vin

--seed and --type

--vin and --gen
