hanja field should be an array type in datapackage.json

[garfieldnate]

May in fact be better to generalize the concept to simplify alternative spellings.

Working notes:

hanja field should be an array:
- 淵魚,鰱魚
- 俛,袝
- 남동생 男同生 can also be written 男동생
- 청사초롱 靑紗초籠 can also have 燭 I feel like the 초 is 灯; but it's not kyoyuk
- 어음교환조합은행 can appear with spaces: 어음교환 조합은행 or 어음 교환 조합 은행, etc.
- 最정상급 for 최정상급 might get used instead of 最頂上級
- should 어음 交換 be also 語音 交換? Online they seem to use hangeul everywhere, but the etymology seems sensical...
