pre-release v0.51

This version has been verified to work on data exports from Qualtrics for ongoing studies by the Family and Culture Lab as of February 2023. It features a reworked GUI, the underlying code was refactored to use more modern tooling, support was added for *.csv files, support for additional charsets was introduced, and most importantly, a bug fix for saving the analyzed data as *.tsv (and now *.csv as well) was included.
