isSupersetOf<T>(
seq: Iterable<T>,
setFactory?: SetFactory<T>,
): (src: Iterable) => boolean
Determines whether the source iterable contains every element from the comparison sequence.

Curried version of _isSupersetOf.
Type Parameters
- T

Parameters
- seq: Iterable<T>
  Iterable whose contents are required to appear in src.
- setFactory: SetFactory<T> = ...
  Optional factory supplying the set used for membership checks.
Returns (src: Iterable) => boolean
true when src is a superset of seq, otherwise false.

Error Rethrows any error thrown by setFactory.
Example
```
const result = _isSupersetOf([1, 2, 3], [1, 2]);
console.log(result); // true
```
or using the curried version:

const result = pipeInto(
