The Sunqua Peak patch released on 2020-09-15 shifted fractals around
(notably moving the old CMs to 98 & 99), which messed with the boss
health in those fractals. As a result, the Skorvald CM detection (which
relied on the health of Skorvald being higher in CM) was broken.

This patch introduces a fallback mechanism which relies on the
split-phase anomalies, as those are still different in the CM. It should
be 100% accurate, as long as players actually make it to the split
phase. Before that, we currently have to assume that the fight is
non-CM, even if it's a log from a CM wiping before first split phase.

There is some discussion in the Elite-Insights Discord here[1] about
this change.

Since downstream applications will also print this, we should remove it.

This was only there to make it easier to gradually implement the outcome
method for the individual bosses. Now that each boss has a proper
outcome, we no longer need the default method - in fact, I'd rather make
sure the compiler tells us if we forget to implement this method in a
new analyzer.
