Optimizing application of the ignore-list of nodes for AlphaJumpDetector.

Instead of building the full path of each node, and then searching it in the PATHS_TO_IGNORE set, we are descending the tree of the nodes to ignore. This saves us building the whole path for each node.

Now that AlphaJumpDetector has more fields specifically for alpha jump detection in AnalysisNode, I’ve introduced an abstraction of per-detector data in AnalysisNode, see the ‘detectorsData’ field. Each detector (alpha jumps, flash, position jump), will be able to add its own data to AnalysisNode without polluting it.
