Revert "Merge pull request #2879 from fonttools/drop-py37"

This reverts commit 66a3ec90713375aec5a95d1698ef1521fd432918, reversing
changes made to 82b90236f839fc9fc8e694ddcdee0ad1604d30ec.

A major user of fontTools, RoboFont, will need a bit more time to wean itself from Python 3.7.
We can delay this change by a few more months to give them time to upgrade.
