Option sticker decoding

[noboco]

Hi there guys,

we have reproduced tens of underhood option stickers and warranty book option stickers so far.
This enabled us to gain knowledge needed for decoding the stickers.

If you would need it, go ahead and let me know.

We can decode the following:
- country of delivery
- year of production (but not month)
- type of engine and gearbox
- exterior color
- interior color
- additional options
