Added Pinyin transliteration to Chinese sky culture.

Seems a lot of work, thank you. I cannot discuss correct spelling with you, so I must assume this is correct. It is only a data change, so I approve.

However, it reminds me of the fact that we must deal with skyculture and language issues sooner or later. (Rather later in 2020.) The number of translatable strings is exploding, and this is a case for untranslatable strings. Or would Pinyin transliterations be translated/translitered again to other scripts systems?

Google Translate can display pinyin while typing Chinese.

It should be difficult to transliterate into other languages again, and seem to be treated as untranslatable strings.
Pinyin can accurately express the pronunciation of Chinese characters by defining the pronunciation of each Latin letter. The system includes four diacritics denoting tones. It is difficult for other letters to reconstruct a set of spelling rules. It can also be used if denoting tones is cancelled, but it will cause a lot of homophones. (In fact, homophones cannot be completely avoided even with denoting tones.)

Added Pinyin data should be untranslatable here, but we do not support this scheme in planetarium at the moment. Seems this is new one good point for catch into the specification of second edition of skycultures (and unification of course).

I know, it may be not very good from developers side, but this is very good for translators side - could you add comments for translators for Pinyin strings?
