Add a workaround for the sips-atos.com domain deprecation

sips-atos.com is going to be retired at the end of this month, and there's no release in sight in the version of the library this module depends on to get the new URLs in there.

As a workaround, this module is going to replace the old domain with the new one to keep things working.

Setting to major, because without this or the official library being updated, everything will stop working in July. Probably going to create a release after commit.
