This method can be used to remove annotation pages from a multi-page annotation file. The page number is 1-based. Therefore, the first page is page 1, the second page is page 2, and so on. This method can be used for all LEAD annotation file formats. To determine the format for a particular LEAD annotation file, use AnnCodecs.GetInformation.
Note, you cannot delete a page from an annotation file that has only 1 page.
