Matcher for a non-empty string.

Matchers are applied through assertObjectMatches, where they narrow the corresponding property type.

Type information that already exists in the calling scope is incorporated.

## Usage

```ts
import { assertObjectMatches, nonEmptyString } from "@kensio/smartass";

const value: unknown = {
  sequenceNumber: "49590338271490256608559692538361571095921575989136588898",
};

assertObjectMatches(value, {
  sequenceNumber: nonEmptyString(),
});

// value is now narrowed to an object with a non-empty sequenceNumber
// {
//   sequenceNumber: string & { 0: string };
// }
```
