   ERR Not implemented: DeleteRange unsupported in WriteBatchWithIndex
   rocksdb ref: https://github.com/facebook/rocksdb/blob/c72ee4531b288bf08b9414155fafb86cc4378fb4/include/rocksdb/utilities/write_batch_with_index.h#L165
   
   ### Anything Else?
   
   I discovered this issue while trying to solve https://github.com/apache/kvrocks/issues/2310. One of my solutions in issue-2310 was to imitate the current transaction implementation and use WriteBatchWithIndex
   > issue-2310 
   > 2. Get WriteBatchWithIndex in GetWriteBatchBase, but I found that WriteBatchWithIndex cannot support all operations of WriteBatch, such as DeleteRange. Even after using WriteBatchWithIndex::GetWriteBatch after DeleteRange, we cannot index the effect of DeleteRange in Batch through GetFromBatchAndDB.
