ComparatorDimensionDictionary (druid-processing 28.0.1 API)

java.lang.Object
- org.apache.druid.segment.ComparatorDimensionDictionary<T>

```
public class ComparatorDimensionDictionary<T>
extends Object
```
Comparator based DimensionDictionary there are a lot of unused methods in here for now since the only thing this is used for is to build up the unsorted dictionary and then it is converted to a ComparatorSortedDimensionDictionary, but leaving the unused methods in place for now to be basically compatible with the other implementation. This version is not thread-safe since the only current user doesn't use the dictionary for realtime queries, if this changes we need to add a 'ConcurrentComparatorDimensionDictionary'.

  - estimateSizeOfValue
```
public long estimateSizeOfValue(T value)
```
    Estimates the size of the dimension value in bytes. This method is called only when a new dimension value is being added to the lookup.
    
    Throws:
    
    UnsupportedOperationException - Implementations that want to estimate memory must override this method.
