Francis Clarke's campaign to fix all the relative number field bugs over
the last couple of months -- but presumably we can close this ticket now?
Yes, this issue had already been raised in #4738, and I commented there
that "The problem of the slowness of computing relative maximal orders is
solved by the patch in #5842. A doctest is included at line 532 of the
patched `number_field_rel.py`" (It's become line 570 by 4.1)
What changed was a rewrite of `maximal_order` for relative number fields.
The previous version was repetitive and grossly wasteful of memory.
