FS#569 - Figure out image processing algorithms for CP-98xx family
They're an older-generation of the D70 family's. Data tables are unfortunately embedded inside the drivers, which makes this a lot more challenging. Sigh.
(If nothing else, simply obtaining the RGB->YMC conversion/gamma tables would make the printers immediately useful..)

On the CP-9810/9820, low-hanging fruit is to use the pre-generated matte data file instead of attempting to generate it for ourselves.
Matte data plane in theory can now be read off of disk. Untested, naturally.
Managed to extract the data tables. Only 8bpp->12bpp gamma tables are decoded.
A ton of work to have the backend do this work. Needs testing.
First pass (gamma) confirmed to work. Anything further will require considerable RE effort.
Tester popped up. Turns out the new code was _quite_ broken. I fixed several major bugs, but tester disappeared on me before I could confirm things were indeed okay.
