/**
* Creates an array of unique values that is the symmetric difference of the given arrays using a custom comparator function.
*
* The symmetric difference is the set of elements which are in either of the arrays,
* but not in their intersection, determined by the comparator function.
*
* @template T - Type of elements in the input arrays.
*
* @param values - The arrays to inspect, or the comparator function.
* @returns An array containing the elements that are present in exactly one of the arrays
*  as determined by the comparator.
*
* @example
* // Custom comparator function for objects with an 'id' property
* const idComparator = (a, b) => a.id === b.id;
* xorWith([{ id: 1 }, { id: 2 }], [{ id: 2 }, { id: 3 }], idComparator);
* // Returns [{ id: 1 }, { id: 3 }]
