v1.14.0

Features

• Support for creating hidden columns by using ColumnOptions.Hidden. Thanks to @BredStik for the contribution!
• The ColumnHeader attribute can now reference resource files (ResX) to have localized header names. For example, to reference a resource key Header_FirstName from resource file MyResources.resx:

  [ColumnHeader(typeof(MyResources), nameof(MyResources.Header_FirstName))]
  public string FirstName { get; }

  Note that the resource file must have a public access modifier. A row of header names can then in turn be created in a worksheet by calling Spreadsheet.AddHeaderRowAsync. This feature is not just limited to resource files, and can also similarly reference other public static properties.
