Use actix_web::main for main function

[AMythicDev]

The actix_web's newest stable release re-exports actix_rt::main. So you probably should change your main function to this

#[actix_web::main]
async fn main() -> std::io::Result<()>  {

And append main to the use line of actix_web in the main.rs file.

You should also probably remove actix-rt from the dependencies list in your Cargo.toml because I do not see any other use for it.

I should have filled up a PR but I didn't had the time to fork, change and file it. Also I didn't fully studied your codebase
