0.22.2

Added

• futhark repl is now delightfully more colourful.

• futhark repl no longer prints scalar types with type suffixes (#1724).

• futhark pyopencl executables now accept --build-option.

• New functions: f16.nextafter, f32.nextafter, f64.nextafter,
  matching the ones in the C math library.

• futhark literate now prints directives in the output exactly as
  they appear in the source.

Fixed

• Diagnostics will no longer contain control codes when output is a
  file.

• CLI executables now fail when printing an opaque instead of
  producing garbage. This improves handling of some incorrect uses of
  auto output (#1251).
