feature: text cleaning / normalization

[MadBomber]

After spiting the text the typical next step is sometimes to clean (aka normalize) if before before indexing or vectorization processes. Here is the class that I wrote. It might be an interesting new feature to add to baran.

I think the TextCleaner class is too small to be a stand-alone gem. It might fit in well with your project.
