Bump euclid to 0.22

- Also updates raqote to latest with an upgrade of font-kit to 0.11
  applied on as a patch
- Update lyon_geom to the latest version

Major change:

- All matrices are now stored in row major order. This means that
  parameters to rotation functions no longer should be negated.
- `post_...()` functions are now named `then()`. `pre_transform()` is removed,
  so `then()` is used and the order of operations changed.
