Noto Nastaliq Urdu: Version 4.000 added

[simoncozens]

Taken from the upstream repo https://github.com/notofonts/nastaliq at commit notofonts/nastaliq@9887ddf.

PR Checklist:

• Family categorization tags collected from the type design team with the Categories Form
• minisite_url definition in the METADATA.pb file for commissioned projects
• primary_script definition in the METADATA.pb file for all projects that have a primary non-Latin based language support target
• subsets definitions in the METADATA.pb reflect the actual subsets and languages present in the font files (in alphabetic order). For CJK fonts, only include one of the following subsets chinese-hongkong, chinese-simplified, chinese-traditional, korean, japanese.
• Fontbakery checks are reviewed and failing checks are resolved in collaboration with the upstream font development team
• Diffenator2 regression checks for revisions on all projects that are currently in production
• Designers bio info have to be present in the designer catalog (at least an issue should be opened for tracking this, if they are not)
• Check designers order in metadata.pb, since the first one of the list appears as “principal designer”
• Social media formatted visual assets for all new commissioned projects in the Drive directory, communicate with the repository Maintainer so that they can push this content to the Social Media tracker spreadsheet
• Social media content draft for all new commissioned projects in the Drive directory and Social Media tracker spreadsheet, communicate with the repository Maintainer so that they can push this content to the Social Media tracker spreadsheet

[simoncozens]

This is a new major release; when looking at the diffenator report, expect substantial change!

Noto Nastaliq Urdu v4.000

This is a major re-engineering of the font, which fixes most open issues. Dot positioning and bari ye handling has been extensively revised. Some connections have been simplified, reducing the glyphset dramatically.

• ⚠️ WARN

  The following codepoints supported by the font are not covered by
  any subsets defined in the font's metadata file, and will never
  be served. You can solve this by either manually adding additional
  subset declarations to METADATA.pb, or by editing the glyphset
  definitions.

• U+02C7 CARON: try adding one of: yi, canadian-aboriginal, tifinagh
• U+02C9 MODIFIER LETTER MACRON: not included in any glyphset definition
• U+02D8 BREVE: try adding one of: yi, canadian-aboriginal
• U+02D9 DOT ABOVE: try adding one of: yi, canadian-aboriginal

• U+030A COMBINING RING ABOVE: try adding syriac 8 more.

Use -F or --full-lists to disable shortening of long lists.

Or you can add the above codepoints to one of the subsets supported by the font: arabic, latin, latin-ext, menu

@simoncozens Qq, I'm guessing there are empty glyphs since the shaping engine eventually picks an isol, init, medi or fina form so they're kinda redundant?

[simoncozens]

No isol feature, but those particular glyphs are empty because they're immediately decomposed into base glyph + dot glyph in ccmp.

I see some interpolations issues left: ⚠️ WARN Detect any interpolation issues in the font.
