max() is a "getter" method. It returns a DateTime.
You can't use it to set the max value.
Either you create a new set, or you make a "union"
with the new max value.
$dt_set = $dt_set->union(
$dt_set->max->add($dt)
);
OTOH, maybe you need a DateTime::Span instead of
a DateTime::Set:
$dt_span = DateTime::Span->from_datetimes(
start => $dt_set->min,
end => $dt_set->max->add($dt)
);
