1.2.0

Changes since 1.1.x

• ListTag now uses PHPStan generic types. By default, a ListTag will be ListTag<Tag>.
• CompoundTag::getListTag() now supports checking the type of list via a string $tagClass parameter.
  • This uses PHPStan generic inference, so e.g. doing getListTag("name", StringTag::class) will return ListTag<StringTag>|null.
  • An UnexpectedTagTypeException will be thrown if the tag is a list of a different type.
• Added ListTag::cast(), which accepts a string $tagClass and returns null if the list type doesn't match. This uses PHPStan generic inference, so e.g. doing cast(StringTag::class) will return ListTag<StringTag>|null.
• ListTag PHPStan generics will be narrowed by doing any of the following: passing a non-empty array to the constructor, push(), unshift(), set()

Note: If you don't use PHPStan, you won't be affected. These changes mostly benefit static analysis.
