NotSupportedException when decompress a GZIP file

Hi ! We encountered an error with version 0.27 when we tried to decompress a GZIP file. The method MoveToNextEntry() throw a NotSupportedException exception when the code tried to access to the Length property of class SharpCompress.IO.RewindableStream.

You can reproduce this behaviour with the code bellow and the file attached: simple.gz.

FileStream fStream = new FileStream("file/simple.gz", FileMode.Open);
using (SharpCompress.Readers.IReader reader = SharpCompress.Readers.ReaderFactory.Open(fStream))
{
	while (reader.MoveToNextEntry()) // Crash here
	{ }
}
