Libertinus Serif Initials: Version 7.051;RELEASE added

[yanone]

Taken from the upstream repo https://github.com/googlefonts/libertinus at commit googlefonts/libertinus@63b24ea.

Resolves #12

PR Checklist:

• minisite_url definition in the METADATA.pb file for commissioned projects
• tags are added for NEW FONTS
• 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

⚠️ WARN Check if each glyph has the recommended amount of contours. contour_count

• ⚠️ WARN

  This check inspects the glyph outlines and detects the total number of contours in each of them. The expected values are infered from the typical ammounts of contours observed in a large collection of reference font families. The divergences listed below may simply indicate a significantly different design on some of your glyphs. On the other hand, some of these may flag actual bugs in the font such as glyphs mapped to an incorrect codepoint. Please consider reviewing the design and codepoint assignment of these to make sure they are correct.

The following glyphs do not have the recommended number of contours:

- Glyph name: zero	Contours detected: 6	Expected: 2 or 3


Glyph name: one	Contours detected: 3	Expected: 1


Glyph name: two	Contours detected: 3	Expected: 1


Glyph name: three	Contours detected: 3	Expected: 1


Glyph name: four	Contours detected: 4	Expected: 1 or 2


Glyph name: five	Contours detected: 3	Expected: 1


Glyph name: six	Contours detected: 6	Expected: 1 or 2


Glyph name: seven	Contours detected: 3	Expected: 1


Glyph name: eight	Contours detected: 9	Expected: 3
