/**

* For a given leaf index, computes the authentication path and the resulting
|
|
* root node using Merkle's TreeHash algorithm.
|
|
* Expects the layer and tree parts of the tree_addr to be set, as well as the
|
|
* tree type (i.e. SPX_ADDR_TYPE_HASHTREE or SPX_ADDR_TYPE_FORSTREE).
|
|
* Applies the offset idx_offset to indices before building addresses, so that
|
|
* it is possible to continue counting indices across trees.

*
|
|
* This implementation uses SIMD to compute internal nodes 2 at a time (in

* parallel)
