Package loc counts code/comment/blank lines. gocloc provides comment-aware
counting; for languages with no gocloc mapping we fall back to
"non-blank = code" and mark the result not comment-aware.
Count returns the line breakdown for content. enryLang is the language ID
from detection; it is mapped to a gocloc language for comment-aware counting.
Unmapped languages fall back to non-blank=code with CommentAware=false.
