* Fixed bug where dumping a fresh database could write wrong-sized encryption IV, making the resulting
serialization unreadable by some KeePass implementations. Thanks HIGHTOWE.
* Fixed bugs preventing the use of memory protection with fresh databases. Thanks HIGHTOWE.
* Fixed the transform_rounds method to work with Argon KDF; this now maps to the Argon iterations value if
the current KDF is Argon. Thanks HIGHTOWE.
