Query layer

[comath]

• Adds a bulk query structure and migrates to the new pyo3.
• Renames dry_trace to path, as this is more correct and in line with other libraries.
• Adds a cache for the final location of each sample in the training set
• Adds parent address to the node struct so that tracing up the tree is possible
• Adds a known_path query that determines the path of a sample from the training step
