[Feature] If platform is PS3, only add specific file as the rom

[InsertDisc]

Is your feature request related to a problem? Please describe.
When installing PS3 games every file in the folder structure gets added as an installed file. Only PS3_GAME/USRDIR/eboot.bin is a valid launch file. This creates a multitude of entries that need removed to get the correct play action.

Describe the solution you'd like
If the platform is PS3 then only add the above mentioned reboot.bin as the rom file.

Describe alternatives you've considered
The only alternative I have been able to come up with is manually editing a game after install as to not have 30+ play actions..

I am having the same issue with the PC (Windows) platform. I think it should filter based on the Supported File Types in the Emulator configuration. I'm investigating a fix in this file: https://github.com/rommapp/playnite-plugin/blob/v0.2.6/Games/RomMInstallController.cs#L100
