DataFixerUpper Java 8 Support

It would be nice if you can add Java 8 support.

I got the following error if I am trying to build my Java 8 Project:

java: cannot access com.mojang.datafixers.util.Pair bad class file: /${PROJECT}/datafixerupper-8.0.16.jar!/com/mojang/datafixers/util/Pair.class class file has wrong version 61.0, should be 52.0 Please remove or make sure it appears in the correct subdirectory of the classpath.

Why would you need it to support java 8? DO you wnat it to support older minecraft versions? MInecraft hasnt been using Java 8 for a while.

See this project here, it's a gradle plugin that allows you to use newer deps on older Java runtimes, or allows you to downgrade a Jar to an older runtime. https://github.com/unimined/JvmDowngrader

(Honestly though, if you're trying to build for a MC version that uses Java 17 at runtime, just use that Java runtime)
