[Suggestion] Add native language title property

[nanikit]

I can't search the beatmaps in-game by title if they have native language title (e.g. japanese) because in-game input method support only english (even if IM support other language, I wouldn't able to use it).
Also other language users may not be able to read the native title because they don't know the language well.
osu! has TitleUnicode property, separate from Title, that is intended for this problem. So I suggest applying similar approach to this issue.
While it's frustrating that beat saber doesn't support it on its own, waiting for the game to support it will only encourage more problematic maps to be created in the future.
I know it's not easy, but I want it to be considered.
