Hard-code Sapling circuit hashes in zcash_proofs crate
...
Define the spend_hash, output_hash, sprout_hash circuit hashes as constants in the load_parameters function, so we don't have to take them as function arguments.

Refactor zcash_primitives::merkle_tree::CommitmentTreeWitness

- The internal Option wrapper was an unnecessary leftover from when this
code was directly inside the prover, where Some(x) represents an
assigned variable.
- CommitmentTreeWitness::from_slice_with_depth is more idiomatic Rust.

Move merkle_tree::Node into sapling module

This makes the merkle_tree module properly generic over the tree hash.
It still hard-codes a depth 32 tree, because Rust doesn't yet support
generic sizes, and we are unlikely to need to alter the tree depth in
future circuit changes.

The primary reason for migrating is that these crates provide APIs for
