A lot of software gets confused when there are named instances that differ only by opsz. This change removes all "Display" instances from the fvar table and makes opsz=32 the default, so that software without automatic opsz-to-size mapping displays the "Display" styles instead of the text styles by default. This is the same approach taken by Apple San Francisco Pro. Closes #519
