[opentype/STAT/ital_axis] Is reporting a FAIL on static fonts

[guidoferreyra]

Observed behaviour

When processing static fonts you get something like the following:

FAIL :
Font MyFont-Light.otf has no STAT table

FAIL :
Font MyFont-MediumItalic.otf has no STAT table

FAIL :
Font MyFont-Medium.otf has no STAT table

FAIL :
Font MyFont-LightItalic.otf has no STAT table

FAIL :
Font MyFont-Black.otf has no STAT table

I don’t think it should report this as a FAIL. AFAIK, static fonts can have STAT table but is not mandatory and, in fact, it looks like a bug since the code code tries to run the check only on a "vf_collection"

fontbakery/Lib/fontbakery/checks/opentype/STAT/ital_axis.py

Line 158 in 4cc71b3

for roman, italic in segment_vf_collection(fonts):

In addition, the function to find roman and variable fonts relies on file names, I know the "source of truth" has been debated many times but limiting this just to the presence of "-Italic" in the filename it’s too limited to be on the Opentype profile. Font makers uses many different names for Italics and slanted designs.

Expected behaviour

Ommit static fonts
