fetching from urlscan issue #2

[ko2sec]

Hi, I was debugging the tool and noticed that while fetching from urlscan there is an issue.

If the total object number is smaller than 10000, urlscan returns "has_more" field as "false" which makes no sense. As a consequence if the target subdomain has URLs between 100 and 10000 gau does not iterate over another request and it fetches only first 100 URLs.
