Problem statement:

I'm trying to deploy contract built with scarb >= 2.7.0 to sepolia network using recipe from here (kindly provided by @thiagodeev). But all I got was error from the node, stating:

{
     "jsonrpc": "2.0",
     "id": 3,
     "error": {
        "code": 60,
        "message": "The compiled class hash did not match the one supplied in the transaction"
    }
}

As I need this functionality in golang I started digging and realised that library has fallen behind agains the recent casm format, especially it lacks accounting of bytecode_segment_lengths field. That results in incorrect class hash.
