Prior to this commit, there was an internal procedure with the merkle
trees to compute empty sub-tree for arbitrary depths.
However, this isn't ideal as this code can be reused in any merkle
implementation that uses RPO as backend.
This commit introduces a structure that will generate these empty
subtrees values.
This commit introduces the re-export of the listed primitives.
They will be used inside Miden to report the security level of the
picked primitive, as well as other functionality.
