/**
 * Hook that generates a unique id that will retain its value
 * during the lifecycle of the calling functional component.
 *
 * The parameters are either
 * - nothing: a unique id will simply be generated with no prefix.
 * - a string or a number: a prefix to prepend to the generated id.
 * - an object with the following props:
 *    - id: if this is a number or a string, it will be returned as is
 *    - prefix: prefix to prepend to the generated id.
 *
 * @param {string | number | object} options
 * @returns a unique id
 *
 * @examples
 *
 * const someId = useUniqueId();
 * // -> someId = "1j3h4f5"
 *
 * const errorId = useUniqueId("av-text-input-error-");
 * // -> errorId = "av-text-input-error-1j3h4f5"
 *
 * const inputId = useUniqueId({ id: 42, prefix: "av-text-input-" });
 * // -> inputId = "av-text-input-42"
 *
 * const inputHintId = useUniqueId({
 *   prefix: "av-text-input-hint-",
 * });
 * // -> inputHintId = "av-text-input-hint-1j3h4f5"
