Drop Spread 2

The successor to Drop Spread, ported to 1.21.

Adds the dropSpread gamerule, allowing values between 0.1 and 10, where 1 is the default velocity applied to items on death, and 0.1 is the default, as seen in the mod icon.

I tested all the way down to 1.19.2, and can confirm it works all the way up to 1.21.1. On every other version, your mileage may vary. If it doesn't work, go to the original version.

All credit for idea and code goes to jadc, the original author, but given that his github repo hasn't been updated in 2 years, it seemed best to just port it myself.
