This is the first step in differentiating between Encounters and Bosses.
It sounds a bit weird at first, but there are some events without any
bosses (like the River of Souls), and some events which have multiple
bosses (like Twin Largos or the kodan strike mission). If we want to
support this better, without relying on extra IDs, special casing and
constants (like NIKARE_ID), we should differentiate between Encounters
and Bosses.

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.

The sacred texts have been received and can now be used to make sure we
detect the Cardinal Sabir Challenge Mote correctly!

Currently, I seem to not have a Cardinal Sabir CM log though.

This makes sure that at least the basic functionality is working. The
logs are "real world" logs, unmodified, directly from arcdps. Some of
the names have special characters in them, so that part of the code is
tested as well.
