Add final sapling root test vectors (#2243) 
* Add sapling final root test vectors

Also tidy some formatting and imports

* Doc: final sapling roots can be duplicated

* Reverse the byte order of final sapling root test vectors

This makes the test vectors match the byte order in the block header,
rather than the zcashd RPC responses.

* Ignore pre-sapling block header commitments

Previously, Zebra expected this reserved field to be all zeroes,
but some mainnet and testnet blocks had other values.

* Test structural and semantic validation of the block commitment field

History roots are excluded from these tests, because they require
contextual validation.

Some tools don't deal well with unicode text. And we're not using it
consistently in Zebra anyway.
