> The `DeltaByteArrayEncoder` has a memory leak due to a bug in how
> `EstimatedDataEncodedSize` is calculated. DeltaByteArrayEncoder extends
> `encoder` which calculates EstimatedDataEncodedSize by calling `Len()` on its
> `PooledBufferWriter` sink. DeltaByteArrayEncoder however does not write data
> to sink, instead writing data to `prefixEncoder` and `suffixEncoder` causing
> EstimatedDataEncodedSize to always return zero.
