Manually parse game mode types for private matches

[mikechambers]

Dues to this bug it is not currently possible to search / filter private result types in dcliah by game mode. You can only search by:

---mode all_private

It is possible to manually find the correct mode type, by using the hash in directorActivityHash value, to get the DestinyActivityDefinition from the manfiest, and then check the directActivityModeHash value to figure out the specific private mode.

If there is demand / interest for this, Ill consider it.
