Fini Jastrow 6be4335a59 name-parser: Create more usable short (Windows) names 
[why]
The fontname for Windows can be quite unusable, for example
  `CaskaydiaCoveNerdFontCompleteM-`
for several different fonts, as this is the maximum allowed length of 31
characters that is enforced.

The style/weight is completely lost.

[how]
Split the name into base and style (at a dash `-`) and just shrink the
base name. Result for example:
  `CaskaydiaCoveN-ExtraLightItalic`

Use equal approach for the PostScriptName (although it is less likely
that length limit is ever met).

# 'GlyphsToScale': List of (glyph code) or (list of two glyph codes that form a closed range)) that shall be scaled
# Note that this allows only one group for the whle symbol font, and that the scaling factor is defined by
# a specific character, which needs to be manually selected (on each symbol font update).
# Previous entries are automatically rewritten to the new style.
