Extend the `Visit` function so that
it extracts other kinds of links from the document,
such as images, scripts, and style sheets.
== Test
The test should cover all element types that contain links.
These are elements with attributes `src` or `href`.
E.g. `<script>` and `<img>` use `src`, `<a>` and `<link>` use `href`.
`<link>` is used in `<head>` to point to a style sheet.
== Example
Given this example HTML document as input:
[source,html]
----
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<a href="link">a</a>
<img src="imagelink">
<script src="scriptlink"></script>
</body>
</html>
----
the Example function's `Output` is:
[source,go]
----
// Output:
// style.css
// link
// imagelink
// scriptlink
----
