BIP-352: add test vector for exceeding K_max limit [receiver side]

Test case: even though there are 2324 outputs targeted to the recipient,
only 2323 are found due to the introduced K_max limit. Any
implementation following the new BIP protocol rule wouldn't create such
a transaction in the first place, but an attacker might do.

Can be tested by
`$ ./bip-0352/reference.py ./bip-0352/send_and_receive_test_vectors.json`
