Add Chiron Sung HK

[tamcy]

Just like #5323, this issue is a replacement of the 3-year-old issue #1842.

Font Project Git Repo URL:

https://github.com/chiron-fonts/chiron-sung-hk-gf

Note: The original repository is https://github.com/chiron-fonts/chiron-sung-hk, but it doesn't follow the latest repository structure and font file naming as required by Google Fonts. Also the documentation is not compatible as I need to strip the custom axis for the GF version. So I created another repository specialized for GF, which can be seen as some kind of meta-repository. Hope this is OK.

Super short description of the Font Family:

• A typeface for Traditional Chinese users.
• Derived from Source Han Serif CJK HK v2.001. Unlike the HK/TW version which follows the corresponding (voluntary) regional standard, Chiron Sung HK follows some kind of “ad-hoc” standard that is commonly seen in the Traditional Chinese environments (Hong Kong and Taiwan). The glyph forms are usually found in commercial offerings.
• More than 7,000 mappings changed. Among those, about 3,770 glyphs have been revised.
• Integrates the full glyph set of Source Serif 4.
• An italic version is also available, its LGC glyphs are from Source Serif 4 Italic.

Requirements:

I understand that Google Fonts will publish only fonts that matches its requirements, and I can confirm the project meets them (by ticking the cases, or putting x between the square brackets in text mode):

• [x] The entire font project is licensed under the OFL
• [x] There is no "Reserved Font Name" mention in the OFL license
• [x] Family name is unique according to namecheck.fontdata.com
• [x] The font supports at least GF Latin Core glyphset
• [x] The repository respect the upstream repo structure
• [x] The source files are available in the repository
• [x] I read, agree and comply with the full contributing requirements
• [x] I am the author of the font or the author agreed to this submission
• [x] I will maintain the repository

Is the new repo still private? I can't access the link :)

[tamcy]

My apologies. It's now public.

[RosaWagner]

Thanks! It looks good, we'll try to review it and get back to you if it gets accepted :) Be aware that it may take a while though.

Consider upstreaming?
