Unit tests for FS-154 New TransactionId Derivation

[lnsiegel]

Motivation

Added rust unit tests to confirm the new method of transaction_log_id generation for vectors of OutputTxos passed to the TryFrom<Vec<OutputTxo>> implementation for TransactionId.

In this PR

There are two new unit tests added:

1. test_try_from_vec_output_txo_for_transaction_id
2. test_try_from_empty_vec_output_txo_for_transaction_id

The first test creates different sized vectors of OutputTxo structures. The vectors are of size 1 through 10. The embedded TxOut structs are initialized from entropy, so the public keys are unique on each run. Each vector is first scanned for its minimum public key. The vector is then passed to TransactionId::try_from() and the resulting transaction_log_id is asserted to be equal to the vector's minimum public key.

The second test checks that the expected error message is returned when an empty vector is passed to TransactionId::try_from()
