* core: Rewrite PSF parser & add encoder add .sfo hex pattern to /scripts * core/fs: allow to mount path as read-only * common: Add CString wrapper to handle native null-terminated strings * SaveData: rewrite to implement full functionality * mock value for SYSTEM_VER * SavaData: backup features * SavaData: SaveDataMemory features * imgui Ref-counted textures - has a background thread to decode textures * imgui: rework gamepad navigation * PSF: fixed psf not using enum class for PSFEntryFmt (was a standard old ugly enum) - Add null check to CString when itself is used in a nullable field * SaveDataDialog implementation - Fix Mounting/Unmounting check of SaveInstance
