Hotfix/algol 1031

[wischli]

Description

• Adds AnyRelayNumber for Algol, i.e.testnet-runtime feature
• Substitutes the WASM of Algol 1031 with above adjustment into the chain spec
  • This substitution overwrites the current WASM until the spec version is bumped
  • Necessary to be able to point Algol to another relaychain with a lower block number than the current stalled one

  "codeSubstitutes": {
    "209843": "$bytes_to_hex(WASM_FILE_ALTAIR_WITH_TESTNET_FEAT)"
    },

Context

Algol is stalled because the relay chain validators were offline for too long such that finalization is halted. One approach top fix this is to create a new relay and point Algol to that one. See here for details.

How was the WASM hex created?

1. Build WASM

cargo b --release -F testnet-runtime

2. WASM file to bytes to hex

    let mut file = match File::open(ALTAIR_WASM_FILE) {
        Ok(file) => file,
        Err(e) => {
            eprintln!("Error opening file: {}", e);
            std::process::exit(1);
        }
    };

    let mut wasm_bytes = Vec::new();
    if let Err(e) = file.read_to_end(&mut wasm_bytes) {
        eprintln!("Error reading file: {}", e);
        std::process::exit(1);
    }

    // Convert the Vec<u8> to a hexadecimal string
    let hex_string = hex::encode(&wasm_bytes);

[NunoAlexandre]

let mut wasm_bytes = Vec::new();
if let Err(e) = file.read_to_end(&mut wasm_bytes) {
    eprintln!("Error reading file: {}", e);
    std::process::exit(1);
}

// Convert the Vec<u8> to a hexadecimal string
let hex_string = hex::encode(&wasm_bytes);

What ALTAIR_WASM_FILE value was used btw? the compact compress?
