Changes / Fixes

This release fundamentally changes the implementation used for Endec/Codec interop. Instead of always using EDM as the intermediary format, the framework will now try to determine if a format-appropriate (De)Serializer/DynamicOps implementation is available and use it if so. This means that the serialized representation of all data structures should now be both consistent and preserved correctly when in complex nested scenarios, something we hope will alleviate an entire class of bugs. Most of these are related to serialized EDM which turns out unrepresentable in NBT, but other formats might have been affected too
