Geyser now supports block picking for item frames. It checks to see if the item frame has an item in it - if so, it attempts the same block picking process with the item inside (NBT included). Otherwise, it attempts to pick for an item frame item.
This commit also improves item frames by having the internal map store the entity and not the ID - in many situations, this prevents two maps from having to be searched. Additionally, item frames are no longer despawned if an item is placed on them - rather, it waits until the server tells us to despawn the entity.
* Pick block improvements
- Creative block picking is now implemented. If the survival-styled block picking fails, then the item is created, following Java-style mechanics.
- Entity 'picking' is also implemented. The item is crafted using the same mechanics, and the same rules apply as normal block-picking (except it only works in creative mode, following Java.
