Configure count of characters per row and rows per page to render

When processing text files you can adjust page parameters like max characters per line and max lines per page with MaxCharsPerRow and MaxRowsPerPage options that have been added in v21.11.

    try (Viewer viewer = new Viewer("sample.txt")) {
        HtmlViewOptions viewOptions = HtmlViewOptions.forEmbeddedResources();
        viewOptions.getTextOptions().setMaxCharsPerRow(50); // Default value is 85
        viewOptions.getTextOptions().setMaxRowsPerPage(30); // Default value is 55

        viewer.view(viewOptions);
    }

The following screenshot shows the difference when setting setMaxRowsPerPage(30).
