Example usage

src.copyTo(dest)

// unzip whilst copying
src.copyTo(dest,
is = f => new GZipInputStream(new FileInputStream(f))
)

// zip whilst copying
src.copy(dest,
os = f => new GZipOutputStream(new FileOutputStream(f))
)

// be nice to do those like this:
src.copyTo(dest, is = inputStream.file >>> inputStream.buffer >>> inputStream.gzip)
src.copyTo(dest, os = outputStream.file >>> outputStream.buffer >>> outputStream.gzip)

// or better still
src.unzip.copyTo(dest)
src.copyTo(dest.zip)
