Legacy LazyDFU

This is an unofficial backport of LazyDFU for Legacy Fabric, specifically Minecraft versions 1.13.x

LazyDFU is an optimization mod for Minecraft that defers unnecessary initialization work so that it is only performed if required. Specifically, it makes the initialization of DataFixerUpper "lazy" - that is, it will not immediately create the rules required to migrate data from older versions of Minecraft to newer versions until it actually needs to do so.

The code of this backport is the same as LazyDFU 0.1.2, adjusted to legacy mappings.
