Review Comment:
   Cannot have `Equals` and `HashCode` for `PartitionStats` class as 
`StructLike` need to have comparator for `equals()` which forces that class 
extends `StructLike` to hold some more things. Setting comparator while 
serializing and deserializing that class will be a mess. 
   
   Hence, added this util method. Currently used only by tests. But can be 
useful for developers when they integrate partition stats to engines, they can 
use it for their tests. So, kept as a util.
