[WIP] Add method to process multipage tiff page wise

[Copilot]

Thanks for assigning this issue to me. I'm starting to work on it and will keep this PR's description up to date as I form a plan and make progress.

Original issue description:

Hello,

This is really helpful implementation as it keeps updating new tesseract versions.

Please add method in Image.cs class that overrides PixArray process and process tiff files page wise for multipage tiff files from file.
public static Image LoadTiffPageFromFile(string filename, int pageIndex)
{
Logger.LogInformation($"Loading TIFF page {pageIndex} from file '{filename}'");

var pixHandle = LeptonicaApi.Native.pixReadTiff(filename, pageIndex);

if (pixHandle == IntPtr.Zero)
{
    string message = $"Failed to load page {pageIndex} from '{filename}'";
    Logger.LogError(message);
    throw new IOException(message);
}

var img = Create(pixHandle);
img.ImageName = $"{filename}[{pageIndex}]";

Logger.LogInformation("TIFF page loaded");
return img;

}
