* Fix documentation comment
Was missing a slash to become documentation.
* Add documentation link to type reference
Just to help navigation a bit.
* Implement `Transaction::orchard_actions()` getter
Returns an iterator to iterator over the actions in the Orchard shielded
data (if there is one, otherwise it returns an empty iterator).
* Add V5 support for `has_inputs_and_outputs`
Checks if the transaction has Orchard actions. If it does, it is
considered to have inputs and outputs.
* Refactor transaction test vectors
Make it easier to reuse the fake V5 transaction converter in other test
vectors.
* Move helper function to `zebra-chain` crate
Place it together with some other helper functions, including the one
that actually creates the fake V5 transaction.
* Test transaction with no inputs
`check::has_inputs_and_outputs` should return an error indicating that
the transaction has no inputs.
* Test transaction with no outputs
`check::has_inputs_and_outputs` should return an error indicating that
the transaction has no outputs.
* Note that transaction is fake in `expect` message
Should make the message easier to find, and also gives emphasis to the
fact that the transaction is a fake conversion to V5.
