We need to try to keep the video IDs the same as they were before for --download-archive compat

This is the new URL format: https://www.crtvg.es/tvg/a-carta/a-parabolica-love-story

It's impossible to keep the old video IDs since the new/alternative format doesn't specify the video ID in either the URL or the page contents

[bashonly]

add it as a test

[bashonly]

and we could do this

+        if mobj := re.fullmatch(r'[^/#?]+-(?P<old_id>\d{7})', video_id):
+            old_video_id = [make_archive_id(self, mobj.group('old_id'))]
+        else:
+            old_video_id = None

         return {
             'id': video_id,
+            '_old_archive_ids': old_video_id,
