Added Property PdfSaveOptions.EscapeUri

In some cases, user wants to encode the URI e.g. encode “/” character to the “%2F”. Starting from Aspose.Words 18.3, we have added support to escape the URI before writing it into PDF. Please refer to the following article for more detail:
Escape the URI in Output PDF

/// <summary>
/// A flag specifying whether URI should be escaped before writing.
/// </summary>
/// <remarks>
/// Note that if this option is set to <c>false</c> hyperlinks are written "as is",
/// so valid (escaped) URI should be provided in document's model.
/// <para>The default value is <c>true</c>.</para>
/// </remarks>
public bool EscapeUri

Added Property HtmlSaveOptions.CssClassNamePrefix

We have added new feature in this release to add prefix to all CSS class names when document is exported to HTML. A new property HtmlSaveOptions.CssClassNamePrefix has been added in Aspose.Words 18.3. Please read following article for more detail.
Add Prefix to CSS Class Name

/// <summary>
/// Specifies a prefix which is added to all CSS class names.
/// Default value is an empty string and generated CSS class names have no common prefix.
/// </summary>
/// <remarks>
/// <para>If this value is not empty, all CSS classes generated by Aspose.Words will start with the specified prefix.
/// This might be useful, for example, if you add custom CSS to generated documents and want to prevent class
/// name conflicts.</para>
/// <para>If the value is not <c>null</c> or empty, it must be a valid CSS identifier.</para>
/// </remarks>
/// <exception cref="ArgumentException">The value is not empty and is not a valid CSS identifier.</exception>
public string CssClassNamePrefix
    get { return mCssClassNamesPrefix; }
        if (StringUtil.HasChars(value) && !CssEscape.IsValidIdentifier(value))
            throw new ArgumentException("The class name prefix must be a valid CSS identifier.");
        mCssClassNamesPrefix = value;
