This function does exactly what it says. It appends/retrieves raw data
to/from the archive.
This can be used for various purpose. Here are some examples.
a) binary_archive implements the serialization of primitive types through
this interface.
b) suppose you retrieved some binary data from source - like an image
in a format you don't care about - and wanted to store it in archive
to be retrieved later. You could load/save binary to do this.
