add BIP374 test vectors
- test vectors 0..5 are from test_vectors_generate_proof.csv (only those test vectors with secp generator point here) - test vectors 0, 1, 2 are valid test cases - test vectors 3, 4, 5 are invalid test cases - test vectors 6..12 are from test_vectors_verify_proof.csv - test vectors 0, 1, 2 are present in this file too
