Assert that an array does not include a specific element, with type narrowing.

Note that this is an identity match, so an object in an array only fails the assertion by being a reference to the same object, rather than equivalent in value to another object reference.

Note that absence has no type-level witness, so this narrows an unknown value to an array and stops there.

## Usage

```ts
import { assertArrayNotIncludes } from "@kensio/smartass"

const value: unknown = ["editor", "viewer"];

assertArrayNotIncludes(value, "admin");

// value is now narrowed to an array
// unknown[]
```
