Swap duke with other record linkage solution

[coroa]

Describe the feature you'd like to see

The java dependency that duke pulls in seems to make powerplantmatching for especially Windows users difficult to develop and there were discussions whether to try to replace it.

I do not think there is any pressing need, given that the default ppl list is pre-built and can be downloaded w/o java being installed.

BUT: if that was attempted, i'd really like the implementors to consider mismo as an alternative (maybe also after taking a wait and see approach for it to stablize first).

In any case, nick, collected a detailed list of pros and cons for the other more established current recordlinkage solutions: https://nickcrews.github.io/mismo/concepts/goals_and_alternatives/

If you are looking at python solutions, consider dedupe.
I've yet to use it myself, but it looks quite mature.
