* Add sapling and orchard duplicate nullifier errors
* Reject duplicate finalized sapling and orchard nullifiers
Reject duplicate sapling and orchard nullifiers in a new block,
when the block is added to a non-finalized chain,
and the duplicate nullifier is already in the finalized state.
* Reject duplicate non-finalized sapling and orchard nullifiers
Reject duplicate sapling and orchard nullifiers in a new block,
when the block is added to a non-finalized chain,
and the duplicate nullifier is in:
* the same shielded data,
* the same transaction,
* the same block, or
* an earlier block in the non-finalized chain.
* Refactor sprout nullifier tests to remove common code
* Add sapling nullifier tests
Test that the state rejects duplicate sapling nullifiers in a new block,
when the block is added to a non-finalized chain,
and the duplicate nullifier is in:
* the same shielded data,
* the same transaction,
* the same block,
* an earlier block in the non-finalized chain, or
* the finalized state.
* Add orchard nullifier tests
Test that the state rejects duplicate orchard nullifiers in a new block,
when the block is added to a non-finalized chain,
and the duplicate nullifier is in:
* the same shielded data,
* the same transaction,
* the same block,
* an earlier block in the non-finalized chain, or
* the finalized state.
* Check for specific nullifiers in the state in tests
* Replace slices with vectors in arguments
* Remove redundant code and variables
* Simplify sapling TransferData tests
