l.1597 \ifblx at load@version at one

Hi Angelo,

The problem seems to be that \ifblx at load@version at one was renamed to

\ifblx at load@version at legacy in biblatex-3.3.  This happened in commit

09f8438 in the biblatex git repo, which did a lot of renaming.  Phil,

did you intend to keep the old names as legacy aliases?

There are some more problems with other biblatex styles ...
