[Bug] Switch NSPs and XCIs Within Folders Downloaded Incorrectly

[royaltongue]

Describe the bug
When trying to download any NSP or XCI that lives within a subdirectory, PlayNite will download the file with a .zip extension instead of what the original was. This file is the original file, and changing just the extension manually lets it run fine in an emulator.

To Reproduce
Steps to reproduce the behavior:

1. Put a Switch NSP or XCI base game within a subdirectory inside the switch ROM directory
2. Rescan Switch platform within RomM
3. Try to download the game

Expected behavior
File should be downloaded with correct file extension
