Function createDigestAuthorization

createDigestAuthorization(
    wwwAuth: string,
    username: string,
    password: string,
    method: string,
    uri: string,
): Promise<string>
Convenience wrapper: given a raw WWW-Authenticate header from a 401 response, parse the challenge, compute the response hash, and produce the full Authorization: Digest ... header value for the retry request.

This is the primary entry-point used by the Kinetex client's internal digest interceptor. It is also safe to use standalone in any HTTP client.
Parameters
- wwwAuth: string
  Raw WWW-Authenticate header value (e.g. from response.headers.get("www-authenticate")).
- username: string
  Digest auth username.
- password: string
  Digest auth password.
- method: string
  HTTP method in uppercase ("GET", "POST", etc.).
- uri: string
  Request URI path + query (e.g. "/dir/index.html").
Returns Promise<string>
The complete Authorization header value, ready to attach to the retry request.
Example
```
const auth = createDigestAuthorization(
  'Digest realm="testrealm@host.com", nonce="dcd98b7102dd2f0e8b11d0f600bfb0c093"',
  "Mufasa",
  "Circle Of Life",
  "GET",
  "/dir/index.html"
);
// "Digest username="Mufasa", realm="testrealm@host.com", ..."
```
