Add disc drive key rewrite feature

[AlexEnDrama]

Hello,

For total disc drive replacement when we haven't the genuine disc drive's pcb to do a physical change, it will be great if we can be able to rewrite the disc drive key in order to match it with the corresponding wii u nand key.

Great Day.
Sincerely,

Alex

Doing this requires reprogramming either the Wii U's SEEPROM to match the drive PCB, or the drive PCB to match the Wii U. Both methods have issues:

1. Reprogramming the Wii U's key requires having the new key, and it's unknown if there's a way to obtain the key from the drive directly.
2. It's unknown if there's a way to reprogram the drive's key once it's been programmed the first time.

This seems like a useful feature, but I do understand the challenges in trying to figure out if this is possible or not.

@GaryOderNichts look into PS3 and PS4 drive remarry homebrew. They have a way to dump keys.

Those tools work by sending PS-drive specific vendor commands to the drive. This might apply to the PS3 and PS4, but doesn't work for the Wii U drive.
