message: feat(reakit-utils): Remove `Omit` type
  BREAKING CHANGE: `Omit` has been removed from `reakit-utils/types`. [TypeScript now supports it natively](https://www.typescriptlang.org/docs/handbook/utility-types.html#omittk).
diff: /** @module types */
  import * as React from "react";

  -export type Omit<T, K extends keyof T> = Pick<T, Exclude<keyof T, K>>;
