stand: Revert adding Spleen 32x64

[ziaee]

Summary

Adding a bigger font exposes a bug in the loader font selection which
causes 1080p displays to get too big of a font if one is available. Revert this commit until
someone more knowledgable can improve the font selection algorithm.
Further, I did make a mistake in the linked commit message, it does say
"Reviewed by" where it should mostly say "Discussed with", except emaste
who was actually absent from the discussion except being mentioned.

Pointy-hat: ziaee

IMO you don't get the privilege of wearing the hat just because you didn't have a smaller display to test on. I don't think it's unreasonable to expect that we would choose a sensible font with all of these options at hand.

Closing, tsoome committed the fix for the bug this exposed this today.
