Sorachi's Character Pack for Ring Racers v5

v5 of my character pack is finally here, bringing in three new characters and the first new ones to be made since the release of Ring Racers! Releasing today are Rulue from Puyo Puyo, Bob Bobowski from SMG4, and Yarn Yoshi from Yoshi's Woolly World!

In addition, Lumina, Void and Meggy have received a few touchups, mainly cleaner minimap icons and a different glancing expression for Meggy, and one of Papyrus' rivals has been changed.

I had planned to release these three new characters for SRB2Kart simultaneously with their Ring Racers counterparts, but I have yet to backport many of the updates to the other 10 characters, so I'm releasing the Ring Racers versions now and bring them to SRB2Kart later in a parity update.

This is just a quick hotfix to make some last-minute adjustments now that the character pack has been approved for release.

This hotfix is mainly just for Pepelogoo and Meggy, with the former having some further sprite adjustments and the latter having her rivals adjusted to work with the Mario from mit's Girlpack. All other characters have not been altered.
