[why]
When we rename a font we should always also change the unique ID.
[how]
Take the fullname and the Nerd Font version number. In general we do not
have the version number in the NameParser object; but we have the
'Version' name and we loot the last word (which we have set to the Nerd
Font version already in the patcher) as version descriptor.

[why]
Sometimes we set an empty string as SubFamily name. That ends up as
'Book' which is unexpected.
[how]
The translation from empty to "Book" is done by Fontforge, at least
with version 20220308.
Make sure we always have a SubFamily, and if we don't that must be a
'Regular'.
[note]
This was only a problem with the old naming engine. --makegroups got
this right always.

[why]
The naming has bizarre blanks strewn in sometimes,
or is all caps. For example
`C a s k a y d i a C o v e` or
`CASKAYDIACOVE-Regular`
[how]
When run under Python2 all strings are unicode strings because
`unicode_literals` is imported by `font-patcher`.
Unfortunately the code checks for type str; but that will all become
type unicode with the import.
One check is suboptimal anyhow and can be dropped, while the other is
turned around.

[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).

fontforge has an undocumented call to set the fsSelection bits.
Never rely on documentation :-(
Found this here:
https://github.com/fontforge/fontforge/issues/3174
And the readback values are actually not read from the source font, so
we do not use them.

[why]
Under certain circumstances the WWS names (Family and Subfamily) are
used to identify a font. We do not touch these SFNT table entries, so
when the font is renamed these are wrong (have the original name).
Font-grouping will go wrong then.
[how]
The typographic ('Preferred') Family and Styles are set correctly
already and they follow the WWS pattern, so the WWS fields can be (and
should) be empty. They exist to allow font grouping in the case where
the typographic names do not follow that pattern.
Remove preexisting WWS entries (because they are not needed anymore,
otherwise we would need to write the corrected new names there).
We already set the WWS bit in fsSelection that is needed:
def fs_selection(self, fs):
"""Modify a given fsSelection value for current name, bits 0, 5, 6, 8, 9 touched"""
[...]
b |= WWS # We assert this by our naming process
return b
Unfortunately we have no way (jet) to set fsSelection.
This is only the case for Iosevka for all fonts in src/unpatched-fonts.

DO NOT MERGE
[why]
A lot of the fonts have incorrect naming after patching. A completely
different approach can help to come up with a consistent naming scheme.
