shadPS4 support creates duplicate games when "Enable Separate Update Folder" is enabled

[JupiterJesus]

Bug Description

shadPS4 recently added a feature to keep updates separate from the main game. They are placed in a directory immediately next to the game install, with the name CUSAXXXXX-UPDATE. The naive scanning script implemented in the latest Playnite update finds the EBOOT.BIN in both the main game and the update, adding two games to the library.

I implemented my own scanning script before this update, and already fixed the bug. All I did was add a powershell filter on the packages folder that only accepts directories named CUSA#####. If there are other filename patterns for legitimate ps4 packages, I haven't seen them, but the code could easily be updated to handle them. The relevant code is below. Use it or don't.

[array]$games = Get-ChildItem -LiteralPath $ImportArgs.ScanDirectory -Recurse | Where-Object { $_.DirectoryName -match 'CUSA\d+$' } | Where { $_.Name -eq "ISO.BIN.EDAT" -or $_.Name -eq "EBOOT.BIN" }

To Reproduce

Install a package with shadPS4.
Enable the "Enable Separate Update Folder" in shadPS4 general settings
Install an update package with shadPS4.
Scan for PS4 packages.
