Updated the author's and committer's email address.

While the README states that "Requires Python > 3.6", the build was run for Python 3.6 as well. Since the walrus operator only introduced in Python 3.8, I still should not have used it. The commit avoiding to use walrus operator could be squashed (fixed up) with the commit adding the serializer. Should I do it?
