Bug: stats tracking and display might conflict with GodSeeker+'s extra portal

P5 and segments have the same keys. The only difference before entering the fights are the description text.

• There is some difference in segments that some of them start with a bench, but not all of them. So this cannot be used as a rule.

Sequence detection need something to tell that P5 and segments are different.

Current sequence detection rely on scene change, and such logic is broken by the bench before each segments.

One solution is to use challenge menu to detect sequence change, and treat P5 and segments the same.

Another solution is to use bench also to detect sequence change. This way, P5 and most segments can be treated differently. But there are two shortcomings: (1) first segment cannot tell if it's the segment, or the P5; (2) it highly depends on GodSeeker+'s segment setup.
