Swap duke with other record linkage solution

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/

Review how the current Duke dependency is used in powerplantmatching and assess the Windows development impact described in the issue. Read Mismo's linked goals and alternatives, along with the established record-linkage options, before proposing a replacement. Done would require an agreed alternative and a working migration that preserves the project's record-linkage behavior without requiring Java.
