Dictionary selection #151

Hi. The go-diameter defines several dictionaries (e.g. Gx, S6a, Swx…) and incorporate all of pre-defined dictionaries when it initializes. The application support status is exchanged between client and server in CER/CEA. In most cases a diameter client or server support limited applications and handlers. For example, HSS connecting to MME only needs to support S6a related handlers (e.g. AIR, and ULR). If the HSS informs that the HSS supports Gx, Swx or other non-supported applications, the MME misunderstands the HSS capabilities, which may lead unexpected failure. Is there any possible way to disable to include unnecessary dictionaries?
