Matcher for a numeric value less than the given value.

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

## Usage

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

const value: unknown = {
  retrievability: 0.42,
};

assertObjectMatches(value, {
  retrievability: lessThan(1),
});

// value is now narrowed to an object with a numeric retrievability
// {
//   retrievability: number | bigint;
// }
```
