fix: Removes GetObjectsInRange and fixes boat planks closing (#1579)

## BREAKING CHANGE

- Deletes `map.GetObjectsInRange` and `map.GetObejctsInBounds`

### Notes

Developers are expected to enumerate mobiles and items separately now using `map.GetMobilesInRange` and `map.GetItemsInRange`. This helps keep the code streamlined so we don't have to maintain multiple copies of ref struct enumerators that do the same thing.


### Fixes

- [X] Fixes bug with planks closing
- [X] Fixes issue with iterating items/mobiles from a null map
