Add lzop compression support
file and magic error out when handling lzop compression types Workaround is to find lzop header first if it exists by searching for its hex value TODO - fix file and magic to read lzop compression types properly and eliminate this workaround Currently this method uses busybox for handling lzop compressions. Insure busybox supports lzop or else this will fail TODO - compile lzop statically and eliminate the need for busybox having lzop support
