First Successful Key Lookup

You are given a function get(ctx, address, key), which retrieves a value for a given key from a remote address. However, you don't know which address has the value, and network calls can fail.

Your task is to implement the Get function that:

• Calls get for each address in parallel.
• Returns the first successful response.
• If all requests fail, returns an error.
