Convert object properties to snake case but not recursively.

This can be useful when, for example, converting some API types from a different style.

@example
```
import type {SnakeCasedProperties} from 'type-fest';

interface User {
	userId: number;
	userName: string;
}

const result: SnakeCasedProperties<User> = {
	user_id: 1,
	user_name: 'Tom',
};

const splitOnNumbers: SnakeCasedProperties<{line1: string}, {splitOnNumbers: true}> = {
	'line_1': 'string',
};
```
