Support arrays

[StringEpsilon]

Failing test:

[TestMethod]
public void ExplicitToArray() {
	var result = PhpSerialization.Deserialize<string[]>("a:3:{i:0;s:5:\"Hello\";i:1;s:5:\"World\";i:2;i:12345;}");

	CollectionAssert.AreEqual(new string[]{ "Hello", "World", "12345" }, result);
}

Basically: Support object[] and so on.
