Once all compression parameters are selected,
it's possible to load the target dictionary, using ZSTD_CDict_loadDictionary().
Dictionary content will be copied internally, except if ZSTD_p_refDictContent is used.

After loading the dictionary, no more change is possible.
The only remaining operation is to free CDict object.
Note : An unfinished CDict behaves the same as a NULL CDict when referenced into a CCtx.
