Javadoc
Writes the given 64-bit Unsigned Long to the given byte array at the given offset. This value can then be
deserialized using
#readUnsignedLong. This method is not interoperable with
#readLong.
The advantage of serializing as Unsigned Long (vs. a normal Signed Long) is that the serialization will have the
same natural order as the input value type (i.e., if compared using a lexicographic bitwise comparator such as
ByteArrayComparator, it will have the same ordering as the typical Long type).
