Soft check for PNU spell checkers

The vanilla PNU checker corrects complex words that are unrecognizable by placing spaces between letters. Some common academic and technical vocabulary (초연결지능, hyper-connected intelligence) fail this check. hanspellr disables this feature as default. To enable spell checks for complex words, set soft.check argument as FALSE like:

checked <- hanspellr::spell_check("초연결지능의 영향을 받았다.", soft.check = F)
checked$text_corrected
