[REQUEST] Display missing/available Update and DLC content for a given cart, please.

[RanceJustice]

Hello, I recently came across your program for management of my digital Switch collection. It has many nice features, but one that I think would be very helpful would be querying for and displaying possible Updates and DLC for a title added to your collection, be it XCI or NSP. Thus, users could be aware of the newest available updates and DLC content for their titles.

Switch Backup Manager already queries certain locations for game information (ie nswdb , the official game's info pages etc) so perhaps it could use others to find latest game updates and available DLC. Perhaps info on updates and DLC could also be added to the Releases tab (the Scene releases updates, DLC, and other fixes as well ) , but for now I'll focus on the player's collection.

When the user adds a base-game type file (be it XCI or NSP), information on related components would be displayed below, indented, with each entry showing the pertinent info in fields as needed. For Updates, there would be an option to show all known updates for the title, or simply only to show the latest one. DLC would come after Updates, in a similar fashion. By default, missing Updates or DLC are "greyed out" so users could easily see which they have and which they don't. If a qualifying package is added, it will take on the "normal" coloration of orange for update, green for DLC. etc.

Keeping in mind I'm only listing Game Title in my rough example, please note that in actuality all the relevant fields would be filled, it may look something like this:

The Legend of Zelda: Breath of the Wild
-The Legend of Zelda: Breath of the Wild 1.6.0 [UPD] * (Asterisk indicating latest, all others can be hidden if user prefers)
-The Legend of Zelda: Breath of the Wild 1.5.0 [UPD]
-The Legend of Zelda: Breath of the Wild 1.4.0 [UPD]
-The Legend of Zelda: Breath of the Wild 1.3.0 [UPD]
-The Legend of Zelda: Breath of the Wild 1.2.0 [UPD]
-The Legend of Zelda: Breath of the Wild 1.1.0 [UPD]
-The Legend of Zelda: Breath of the Wild Expansion Pass [DLC]
-The Legend of Zelda: Breath of the Wild DLC Pack 1 [DLC]
-The Legend of Zelda: Breath of the Wild DLC Pack 2 [DLC]

This is only a rough example, but adding this sort of feature will allow users to curate their collection and be aware of the latest updates and DLC for their titles. Thank you for your work on this open source project!
