Adding Err.from

[rjkz808]

In my opinion, typing new Err(new Error('...')) or even Err(new Error('...')) feels kinda wrong and self-repetitive. Maybe it'll be a good idea to add a simple static method like this:

export class ErrImpl<E> implements BaseResult<never, E> {
    // ...

    static from(message: string): ErrImpl<Error> {
        return new Err(new Error(message));
    }
}

This will help everyone to reduce the amount of boilerplate code

function run(): Result<void, Error> {
    return Err.from('...');
}

It's better named as Err.of
