[merge] Duplicate glyphs kept due to irrelevant differences

See original GitHub issue

When merging different Noto fonts, I have found that a lot of duplicate glyphs are kept due to irrelevant differences, like different contour starting points or advance widths.

For example, this is “slash” in “NotoSans-Regular.ttf”:

[('moveTo', ((362, 714),)), ('lineTo', ((96, 0),)), ('lineTo', ((10, 0),)), ('lineTo', ((276, 714),)), ('closePath', ())]

And this is “slash” in “NotoSansAnatolianHieroglyphs-Regular.ttf”:

[('moveTo', ((10, 0),)), ('lineTo', ((276, 714),)), ('lineTo', ((362, 714),)), ('lineTo', ((96, 0),)), ('closePath', ())]

I think the glyph disambiguation feature should be optional and maybe off by default, at least until a better heuristic has been devised.
