    (ffi/write ffi-type data &opt buf index)

    Append a native type, `ffi-type`, to a buffer as it would appear in 
    memory. This can be used to pass pointers to structs in the ffi, or 
    send C/C++/native structs over the network or to files. Returns a 
    modified buffer, `buf`, or a new buffer if not supplied.
