This updates the candidate_list module to use format=binary format instead of format=json. For large projects with many candidates the encoding of the data to JSON can use up all the server's memory and then crash with an out-of-memory error. Since the format=binary format is a line-based streamable format, it does not require loading the entire result set into memory before transmitting it to the client and larger data sets can be loaded into LORIS.
