Add (1G+1U+1D) to SuperNSP / SuperXCIs that have respective games, updates, & DLCs embedded

[NikoMuffin]

Referencing trembon's request for a new thread for the feature request in #81

Here's the request: when SAK or (I think) NSC_Builder combined NSPs to SuperNSP, it tags (1G+1U+1D) into the file name suffix so the user knows what is inside the file.

1G = 1 Game
1U = 1 Update
1D = 1 DLC

File name examples:
Nintendo World Championships NES Edition [0100AD10185F8000] [v131072] (1G+1U)
became
Nintendo World Championships NES Edition [0100AD10185F8000][v131072]
