  9. def calculateChecksum(data: Array[Byte]): Int

    Calculate checksum of a serialized deletion vector.

    Calculate checksum of a serialized deletion vector. We are using CRC32 which has 4bytes size, but CRC32 implementation conforms to Java Checksum interface which requires a long. However, the high-order bytes are zero, so here is safe to cast to Int. This will result in negative checksums, but this is not a problem because we only care about equality.
