This is going to need a rebase, which can be a nightmare with binary files. Suggestion:
# start over with a new branch that's a clean copy of master
git checkout master
git merge upstream/master
git checkout -b prenasalization
# copy over just the changes to the raw file:
git checkout --patch origin/issue#232 raw-data/EA/EA_IPA_correspondences.tsv
# make whatever other changes necessary, then rerun the aggregation
then make a new PR with that branch and close this PR
