ArgumentNullException is thrown if we use AESKeySize = 256. 128 does work

Steps to reproduce

1. Install SharpZipLib.NETStandard on a Xamarin Android Project
2. Execute:

private static async Task AddRawContentToZipAsync(ZipOutputStream zipStream, byte[] rawContent, string fileName) {
   var file = new ZipEntry(fileName) { AESKeySize = 256, Size = rawContent.Length };
   zipStream.PutNextEntry(file); -> EXCEPTION THROWN
   await zipStream.WriteAsync(rawContent, 0, rawContent.Length);
   zipStream.CloseEntry();
}

Expected behavior

Any Exception should be thrown

Actual behavior

An ArgumentNullException is thrown if we use AESKeySize = 256 after we call “zipStream.PutNextEntry()”. It works with AESKeySize = 128
