add

API definition	void add(idx_t n, const float *x) override;
Function	Creates an AscendIndex database and adds new feature vectors into the database. When this API is used to add a feature, its ID is in the range of [0, ntotal).
Input	idx_t n: number of feature vectors to be added to the database. *const float x**: feature vectors to be added to the database.
Output	N/A
Return value	N/A
Restrictions	The length of x must be dims × n. Otherwise, an out-of-bounds read/write error may occur, causing program breakdown. Range of n: 0 < n < 1e9. NOTE: add cannot be used together with add_with_ids. After add is used, the labels in the search result may be duplicate. If the service has requirements on labels, you are advised to use add_with_ids.
