fix: properly implement black/white blending for sprites
...
There's unique rules to handle for BLDY w/r/t sprites, I didn't know
about them (shown in bld_demo.gba). I'm sure I haven't ironed out every
rule but bld_demo.gba now *actually* passes

tmp: disable buggy window emulation
...
I'd like to merge my affine sprite impl into main, which will require
merging a lot of the rewrites I did in this branch. My plan is to
merge the buggy ppu window impl to main, but keep it disabled.
This is technically a regression but the current impl barely worked
anyways so....
