@brief Initialize a native-endian output CDR stream. @component cdr_serializer

Allocates an initial buffer of @p size bytes, or leaves the buffer NULL when @p size is zero. The stream owns the allocated buffer until finalized and serializes using native endianness.

@param os output stream to initialize @param allocator allocator used for stream storage @param size initial stream buffer size in bytes @param xcdr_version XCDR version to use when serializing
