Use long double suffix

Yes, I've seen the commit in master. The only merit this has is that it is consistent with the rest of the usage of doubles. Namely under hardware.

should I note I had disabled the warning in master/next? https://git.magicalgirl.moe/KartKrew/Kart-Public/commit/b9eb5c399be4f37363e87158014e8390f6493560

Should I note this have merge conflicts due to MSVC commits?

added 89 commits

• f0a06662...515fb9ad - 88 commits from branch KartKrew:next
• 62820bb4 - Merge remote-tracking branch 'origin/next' into longdouble

Compare with previous version

Good now?
