Feature request: report distances from stringdist_join() and friends

[lmullen]

For the types of fuzzy joins that have some kind of a distance metric (e.g., a string distance for stringdist_join() and friends), would it be possible to have an option to return the distance measure as a new column in the resulting data frame?

Good idea!

Added distance_col option to those functions (and ability for match_fun in fuzzy_join to return multiple columns generally). Let me know how it works out!

Works brilliantly on some test data. I'll give it a shot with the real data. Thanks so much!
