The marks_modified report outputs the coordinates that have not been modified #60

I compared the two perfectly identical NotoSans-Regular.ttf files using fontdiffenator. A lot of differences of "-1.1368683772161 ..." are reported in marks_modified. I don't think it would be desirable for the report to be output out for unchanged information. The output report is as follows.
