Upgrade yansi: 0.5.1 -> 1.0.1 (#389)

- Adapt to `thing.paint(style)` API; was `style.paint(thing)`
- Remove `yansi::Paint::enable_windows_ascii()` in style usage decision;
  removed in yansi commit b186eb5bfb, which introduced "automatic"
  support for Windows: "If support is not available, styling is disabled
  and no styling sequences are emitted", fitting the `Auto` option
- Respect `--color=always` even if we know it won't work
