0.7.0 (1.20.4)

What's New:

User Changes:

Added arrayFindAny and arrayFindFirst functions to expressions. As the name suggests, those functions will try to find an element of an array or return null if the array is empty.

Added chain function to expressions. This function operates on the results of the first one and allows chaining multiple function calls together like so:

//`it` is the result of the previous function, unless there's a lower level lamda.
chain(arrayOf(2, 3, 6), arrayMap(it, sqrt(it)), arrayFindFirst(it));
//this is the same as:
arrayFindFirst(arrayMap(arrayOf(2, 3, 6), sqrt(it)))

Added remove to cmd:data.
Added cmd:operate to the scoreboard players command.
Added registry access for expressions! Now you can access the game's static and dynamic content registries by using new Registry and DynamicRegistry functions.
- Why is this useful? For example, this allows you to compare item stacks based on their item type:
```
this_entity.getHandSlots[0].getItem == Registry('item').access.chest
```
- For item and block registries there is a shortcut: Item, Block.
```
this_entity.getHandSlots[0].getItem == Item('chest')
```
- Biome and DimensionType are available dynamic registry shortcuts.

Dev Changes:

There's a handful new experimental APIs, which allow you to extend the expression system.

Exposed Object getValue() and Result convert(Object o) in Expression.Result.
Exposed Expression eval(LootContext context, Map<String, Object> parameters) in Expression.
Exposed ProxyMap, ObjectConverter and CustomDataAccessor (which is now a valid data type).
Exposed CustomFields. One of the more interesting APIs. Allows adding new 'virtual' fields to reflective expression objects.
```
static {
  CustomFields.addVirtualField(Entity.class, "nbt", NbtPredicate::entityToNbt);
}
```
