CLI use sitemap

[vvatelot]

Instead of crawling all the website, try to get urls from sitemap

can use https://pypi.org/project/ultimate-sitemap-parser/

I used scrappy sitemap spider because we already used the librairy for another crawler. However, ultimate-sitemap-parser seems quite easy to use, let me know if you want us to use it instead of scrappy.
