Release 0.13.0

Fixed

• string objects passed to scorers had to be strings even before preprocessing them. This was changed, so they only have to be strings after preprocessing similar to process.extract/process.extractOne

Performance

• process.extractOne is now implemented in C++ making it a lot faster
• When token_sort_ratio or partial_token_sort ratio is used inprocess.extractOne the words in the query are only sorted once to improve the runtime

Changed

• process.extractOne/process.extract do now return the index of the match, when the choices are a list.

Removed

• process.extractIndices got removed, since the indices are now already returned by process.extractOne/process.extract
