This PR adds a timeout for reading the response body. The default value for read timeout is 25 seconds. To disable read timeout set value to Duration.ZERO. This can be useful if an HTTP client that supports read timeout is used and an InputStream is passed to RssReader.

Exposing methods for setting connection timeout and request timeout. The default value for these timeouts is 25 seconds, the same as in previous releases.

Example for changing timeout:

var timeout = Duration.ofSeconds(10);

var items = new RssReader()
        .setConnectionTimeout(timeout)
        .setRequestTimeout(timeout)
        .setReadTimeout(timeout)
        .read("https://lwn.net/headlines/rss")
        .collect(Collectors.toList());
