Support for japanese spell checking

[skwolvie]

Request help with how to use this package to perform spell checking of japanese documents.

I am not sure how well this solution works with non-latin scripts. You can see the documentation on how to make a dictionary. If you have success in building a dictionary that works, please put in a PR!

@skwolvie @barrust I think you can achieve that by building an n_grams dictionary
