Implement the support for 7z archives

// Create an instance of Parser class
using (Parser parser = new Parser(filePath))
{
    // Extract attachments from the container
    IEnumerable<ContainerItem> attachments = parser.GetContainer();
    // Check if container extraction is supported
    if (attachments == null)
    {
        Console.WriteLine("Container extraction isn't supported");
    }
    // Iterate over 7z entities
    foreach (ContainerItem item in attachments)
    {
        // Print the file path
        Console.WriteLine(item.FilePath);
        try
        {
            // Create Parser object for the 7z entity content
            using (Parser attachmentParser = item.OpenParser())
            {
                // Extract an 7z entity text
                using (TextReader reader = attachmentParser.GetText())
                {
                    Console.WriteLine(reader == null ? "No text" : reader.ReadToEnd());
                }

        Console.WriteLine("Container extraction isn't supported");
    }
    // Iterate over attachment entities
    foreach (ContainerItem item in attachments)

        Console.WriteLine(item.FilePath);
        try
        {
            // Create Parser object for the attachment entity content
            using (Parser attachmentParser = item.OpenParser())
            {
                // Extract an attachment entity text
                using (TextReader reader = attachmentParser.GetText())
                {
                    Console.WriteLine(reader == null ? "No text" : reader.ReadToEnd());
                }
