1.2.0

• DateTimeOptions now features a list of deserialization formats instead of a single string one. Passing a string instead of an array to its __constructor is deprecated, and will be forbidden in the next version
  Similarly, getDeserializeFormat(): ?string is deprecated in favor of getDeserializeFormats(): ?array
• Added PropertyTypeIterable, which generalizes PropertyTypeArray to allow merging Collection informations like one would with arrays, including between interfaces and concrete classes
• Deprecated PropertyTypeArray, please prefer using PropertyTypeIterable instead
• PropertyTypeArray::isCollection() and PropertyTypeArray::getCollectionClass() are deprecated, including in its child classes, in favor of isTraversable() and getTraversableClass()
• Added a model parser VisibilityAwarePropertyAccessGuesser that tries to guess getter and setter methods for non-public properties.
