Change Date: 4 October 2018
Change Type: Erratum
Change Details: The statement below equation 3.16 about possible multiple embeddings of the N=2 superconformal algebra in N=4 is wrong. The embedding (used later in the paper) is unique. The decomposition of the symmetric product representation is wrong. Below equation 4.8, one should read ? = 1 instead of 2, and ? = 2 instead of 4.
