title: ls filter on channelsftp
body: <p>Are there any way to filter the files to list using this api? for example:</p>
  
  <pre><code>    ChannelSftp sftpChannel;
      sftpChannel.ls(path);
  </code></pre>
  
  <p>This lists all, but I would like to filter the files that begin for AAA for example</p>
