> We call CellUtil#estimatedSerializedSize to calculate the size of rows when scanning.
If the input is ByteBufferCell, the CellUtil#estimatedSerializedSizeOf parses many length
components to get the qualifierLength stored in the backing buffer.
> We should consider using the KeyValueUtil#getSerializedSize.
