Only get the syllable count

[piegamesde]

Many times I am only interested in how many syllables a word has, and not how exactly it is hyphenated. I can get this with hyphenator.opportunities(word).len() + 1, but this is verbose, error-prone (you must know to add 1), and probably inefficient as it allocates a vector. A dedicated helper method to the Hyphentator trait would be appreciated.
