A collection of essential TypeScript types

Convert object properties to pascal case but not recursively.

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

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

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

const result: PascalCasedProperties<User> = {
	UserId: 1,
	UserName: 'Tom',
};
```
