xAvgCharWidth in the OS/2 table is buggy

**Describe the bug**

The xAvgCharWidth in the OS/2 table is 1997 due to a bug in fontforge. The correct value is 1024. (All 0-9A-Za-z (space) widths are 1024)
This value is wrong and causes various bugs (extra spaces between characters, poor hit detection) in wine on Linux and in apps on Windows.

**To Reproduce**

Extra white space between characters in the Microsoft font viewer that starts when you click on a font in Windows.

**Expected behavior**

No extra white space between characters
