Retrieve ECDSA signature R,S,Z values from blockchain rawtx or txid.
The script parse the data of rawtx to fetch all the inputs in the transaction and reconstructs the unsigned message for each of them to find the Z value. The result is given as R,S,Z,Pubkey for each of the inputs present in the rawtx data. [No Internet required]
If txid is given, instead of rawtx then blockchain API is used to fetch the details of rawtx and then R,S,Z calculation starts.
