MultiBreak

• Minimum version number is now 1.21.3
• Fair mode now slows you down to the slowest block, instead of ignoring slower blocks
• Moved particles to the correct blockface on the multiblocks while breaking blocks
• Fixed a bug with powdered snow
• Updated API for more efficient and less frequent calls.

Since prerelease:

• Improved performance while having fair_mode turned on
• Fixed bugs where patterns or break speed would not update at certain occasions
• Fixed an animation bug with block breaks that take 2 ticks
• Fixed a bug where other players can not see breaking progress
• Fixed an error if the player were to disconnect while breaking
