contrib: Adjust output to current test format
Ajust the outputs of gen_base58_test_vectors.py to current test format. 1. Add bech32 vector generation. 2. Add Script-fragments to hexrepr in the format expected by the test. 3. Modify the metadata. 1) Change 'isTestnet' to 'chain' (main/test/regtest) 2) Remove 'addrType' 3) Add 'tryCaseFlip' (True/False on bech32)
