Create a new account

Example:

use flow_rust_sdk::*;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut connection = FlowConnection::new("grpc://localhost:3569").await?;

    let payer = "f8d6e0586b0a20c7";
    let payer_private_key = "324db577a741a9b7a2eb6cef4e37e72ff01a554bdbe4bd77ef9afe1cb00d3cec";
    let payer_private_key_id = 0;
    let public_keys = vec!["ef100c2a8d04de602cd59897e08001cf57ca153cb6f9083918cde1ec7de77418a2c236f7899b3f786d08a1b4592735e3a7461c3e933f420cf9babe350abe0c5a".to_owned()];

    let result = connection.create_account(public_keys, payer, payer_private_key, payer_private_key_id).await?;

    println!("New account address: {:?}", hex::encode(result.address));
    Ok(())
}
