* 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

* Document Ord for Chain and Proof of Work
* Create a NonFinalizedState::new method
And add some debug and clone derives.

As part of this change, add `eq_internal_state` methods,
and proptests for them.
* Check that the chain's nullifiers are not modified on error
* Clarify a test description
* Refactor loop for readability

* Reject duplicate sprout nullifiers in the state
* Improve docs and error messages
* Clarify "must be present" assert logs
* Move nullifier checks to their own module
Also:
* make non-finalized nullifier checks and errors generic over
sprout, sapling, and orchard
* create and update module and function documentation
* Fix a block type name in docs
* Move state assertions or skip them during tests
These changes enable state testing, while still asserting in production.

* Replace assert with expect
* Improve assertion messages
