JP 1baf0e71bb bip360: fix leafHashes order and a control byte in the pqc vectors ...

In p2mr_pqc_construction.json, the three-leaf vectors
(p2mr_three_leaf_complex, p2mr_three_leaf_alternative) listed
intermediary.leafHashes with entries 0 and 2 swapped relative to the
depth-first order of the script tree, while the merkle root,
scriptPubKey, address and control blocks all follow depth-first
order (as do the same trees in p2mr_construction.json).

In p2mr_different_version_leaves, scriptPathControlBlocks[1] started
with byte 0xc1 although the leaf it commits to has leafVersion 0xfa;
the control byte carries the leaf version in its upper 7 bits with
the low bit set, so it must be 0xfb. The vector's leafHashes[1] and
merkle root already correspond to the 0xfa leaf.
