Daira Hopwood 1c10ad5f4a Avoid the need to specify a `rust_fmt` function for Options. 
This does not change test vectors.

Daira Hopwood f8a462d859 Make the test vectors for UAs, UIVKs, and UFVKs match up, and allow unknown items for UAs. 
Also increase the number of test vectors to 20 (10 might be insufficient to see some corner cases).

Daira Hopwood e5d31fea89 Implement ZIP 32 derivation for Orchard and use it for the Unified Address, IVK and FVK test vectors. 
This commit only affects the Orchard test vectors.

Daira Hopwood 68e4ed1ee2 Change the seed used for Unified Address, IVK and FVK test vectors to be deterministic. 
As of this commit, this only affects the Sapling test vectors (we still sample the same
randomness to avoid disturbing the others).

A "diversifier_index" field is added to the Unified Address test vectors. (This is not needed
for UIVKs/UFVKs since they do not depend on the diversifier index for any protocol.)

We also add an "account" field to make the account number explicit, even though it could be
inferred from the test vector index.

Jack Grigg 2093b309f4 Refactor test vectors into package 
Scripts that were previously run via:
    poetry run python ./SCRIPT_NAME.py

and have been moved, can now be run as:
    poetry run SCRIPT_NAME

Some top-level scripts remain, where they only generate test vectors and
do not contain any Zcash logic. These now use the `zcash_test_vectors`
package, and can't be run directly unless this package is made available
in `PYTHONPATH`.
