Lioncash edbbf493f8 DiscIO: Make factory methods return unique_ptrs
Rather than rely on the developer to do the right thing,
just make the default behavior safely deallocate resources.

If shared semantics are ever needed in the future, the
constructor that takes a unique_ptr for shared_ptr can
be used.
