rettiwt.user.details('<username>') seem to require authentication

[improwise]

rettiwt.user.details('') is listed as being able to use as Guest, but when trying to do so, you will get an auth error.

    if (!Groups_1.allowGuestAuthentication.includes(resource) && this.isAuthenticated == false) {
        throw new Error(Api_1.EApiErrors.RESOURCE_NOT_ALLOWED);

rettiwt.tweet.details on the other hand will work without authentication it seems.

Getting user details by using username works without authentication, while getting user details by using id requires authentication.

I didn't clarify it in the README. Will make changes to it asap.

Thanks.
