title: In SpectreConsole, how to strip the tags to get a plain text string?
body: <p>I'm using <code>Spectre.Console</code> and have plenty of <code>AnsiConsole.MarkupLine</code> commands like this:</p>
  <pre class="lang-cs prettyprint-override"><code>AnsiConsole.MarkupLine($&quot;[lime]File size:[/] [bold]\t{file.Length,-10}[/]&quot;);
  </code></pre>
  <p>I'd like to output the same text in plaintext with no color in a text file, like</p>
  <pre class="lang-cs prettyprint-override"><code>var msg = $&quot;[lime]File size:[/] [bold]\t{file.Length,-10}[/]&quot;
  AnsiConsole.MarkupLine(msg);
  var msgclean = AnsiConsole.StripTag(msg);
  LogToFile(msgclean);
  </code></pre>
  <p>Is there a way to strip the tags? Or redirect the console output some way to a file?</p>
