Fix fitting performance writer by changing the measurement comparator

[beomki-yeo]

The measurement comparison operator with float_epsilon is causing a bug in event_data. When the difference between the new measurement and one in the map is bigger than float_epsilon, the measurement is not added to the map.
(You can find the simple code that reproduces this behavior: https://godbolt.org/z/3hP9P5Eo9)

I fixed the issue by removing the float_epsilon. Also put at instead of [] wherever possible to make sure that there is the measurement in the map

No big objections on my part, just the two technical questions/suggestions...

The rest I'm happy with.

And if you push back firmly enough about the whole std::map::insert point, I can drop that as well. Since your code technically already works correctly like this as well. 😉
