Player Motion

Also updated pack format to 1.21.7

When using launch_xyz with a negative y score a much higher value was required to achieve results because of faulty math, this is now fixed. Credit to nedraw.

[DISCLAIMER, applying motion frequently/every tick causes the player to get stuck and sometimes hear explosion noises, due to desync issues and teleport command behavior. Please upvote MC-276722, MC-276704]

Huge shoutout to nedraw from the minecraft commands discord for doing most of the heavy lifting for this release!

• Completely resolves incompatibilities with (terrible) server modding platforms like Paper.
• Much lower complexity; easier to maintain/update!
• Much more efficient; easier on server TPS!
• Works on peaceful mode!
• Now cancels launch function if the player is on a mount.
• Near-perfect launch power parity with the previous method.
