WIP: Support for hard lock with Fanatec devices

[docwilco]

Opened for comments, let me know if people have ProductGUIDs and ProductIDs laying about

[docwilco]

Tested with DD2 and CSL Elite (PS4)

[docwilco]

Not quite ready yet...

Oh my god, that’s amazing, thank you so much! I had to idea how to do it. So is it working now for some devices?

[docwilco]

It's working on a friend's CSL Elite. I still need to test/debug my DD2 some more.

You OK with the code style so far?

[gro-ove]

Sure, although I might run auto-formatter with my settings later if that’s ok. One thing I noticed though looking at those changes, I might be wrong and I do apologize if that’s the case, but it seems as if you’re storing _productIds as private field of FanatecDD2 and then defining new private fields in new classes, but as far as I know, they wouldn’t overwrite original list of IDs. Notice how I was using protected override for all sorts of Fanatec implementations. Maybe that would help?

[docwilco]

Ah, I'm new to C#, and I potentially need to read up on that a bit more. Thanks for the heads up. Is here the best place to communicate, or should I ping you somewhere when I've updated this PR?

Do you have Telegram or Skype (my username is x4fab2)? That would be the best, if possible
