v0.95.3

Bugfixes

• Compile iOS Simulator framework architectures with -fembed-bitcode-marker.
• Fix crashes when the first Realm opened uses a class subset and later Realms
  opened do not.
• Fix inconsistent errors when Object(value: ...) is used to initialize the
  default value of a property of an Object subclass.
• Throw an exception when a class subset has objects with array or object
  properties of a type that are not part of the class subset.
