Add Damerau-Levenshtein similarity matching

[JarbasAl]

is there any other distance function from rapidfuzz that should be added here?

Sorry I did not answer this before. Actually rapidfuzz implements almost all known edit distances/similarities out there but, generally speaking, they are either based on a subset of the edit operations used in the Damerau-Levenshtein distance or add little information to it.

What might be interesting is the weighted mixture of those distances/similarities, which rapidfuzz implements. This comes at the cost of having to tune the weights though.
