TarHeaderFactory Infinite loop

[Ilanlido]

A possible Infinite loop can occur,
Let's look at https://github.com/adamhathcock/sharpcompress/blame/master/src/SharpCompress/Common/Tar/TarHeaderFactory.cs#L51
When the stream that is being used has been closed - for example if the connection was cut, it will keep throw an IOException inside https://github.com/adamhathcock/sharpcompress/blame/master/src/SharpCompress/Common/Tar/TarHeaderFactory.cs#L24
And then and infinite loop of nulls will be here
https://github.com/adamhathcock/sharpcompress/blob/master/src/SharpCompress/Common/Tar/TarEntry.cs#L62
