* Fix geometry of:
- Latin Small Letter B with Stroke (`U+0180`) (#1115).
- Latin Letter Capital Gha (`U+01A2`), Latin Letter Small Gha (`U+01A3`) (#1115).
- Latin Letter Inverted Glottal Stop with Stroke (`U+01BE`) (#1115).
- Latin Capital Letter Hwair (`U+01F6`), Latin Small Letter Hwair (`U+0195`) (#1115).
- Latin Capital Letter Y with Stroke (`U+024E`) (#1115).
- Greek Capital Letter Theta (`U+0398`) (#1115).
- Greek Capital Letter Xi (`U+039E`) (#1115).
- Greek Capital Letter Delta (`U+0394`), Increment Symbol (`U+2206`) under Slab (#1115).

* Variant names of certain letters are renamed, including:
- Upper Gamma (`grek-upper-gamma`).
- Variants for `K`, `k`, Cyrillic Ka (`К` and `к`).
* Add more serifed variants for `K`, `k`, `n`, Cyrillic Ka (`К` and `к`) and Cyrillic Ef (`ф`) to better reproduce PT Mono (#986).
- Cyrillic Ghe with Stroke and Hook (`U+04FA`, `U+04FB`).
- Cyrillic Ha with Hook (`U+04FC`, `U+04FD`).
- Cyrillic Ha with Stroke (`U+04FE`, `U+04FF`).
* \[**Breaking**\]: Rename variants of `A`, `X`, `Y`, `Z`, `x` and `z`.
* Update SS02 and SS16 to better reflect their source fonts (#939).
* Remove unnecessary serifs of Slab Italic Small Cyrillic KA (#938).
* Allow inherit ligations from `calt`
Add `calt` to `hives` so `inherit = 'calt'` works.
Also get rid of `optInBuildup`/`optOutBuildup` because they just
merged into `para.ligation.defaultBuildup`.
* fixup! Allow inherit ligations from `calt`
* fixup! Allow inherit ligations from `calt`
Rename hives
* fixup! Allow inherit ligations from `calt`
Rename `calt` to `default-calt`
