Add parse time to single fusion path

[johannessteu]

Instead of a total parse time it would be cool to see how long it took to render each fusion path

Would you consider this solved with https://github.com/t3n/neos-debug/pull/95 or do you mean "every" fusion path.

Of course each render time of a block with a cache config still contains the render time of it's children. And the information starts to be less correct when subparts are read from cache.
