Convert brand text to YAML

Compared every OCRed record to the original, ordered fields, normalized
formats, structured as YAML. I’ve done this on an airplane (no
connectivity) without a YAML validator, so I assume that there are
plenty of mistakes.
Add all brand images as TIFFs
Fix YAML error
Clean up images

Increase contrast, remove scanning artifacts.
Add images, I guess

I don’t really know how these weren’t part of the prior commit. Anyway,
here they are (again?).
Provide image paths in the YAML

Of course, we’ll change to a different file format, move to an absolute
URL, possibly inline the ASCII-encoded image—this is just a start.
