Add a parsing function for MGT and also detect the EIT tables for ATSC, the EIT pids are reported inside the MGT and we are still only relying only on the table id for detecting it. In the future we would want to also check the pid and compare with whatever the MGT previously reported to confirm that it is indeed the EIT. https://bugzilla.gnome.org/show_bug.cgi?id=730435
