GetFeatures

API definition	APP_ERROR GetFeatures(int n, float16_t features, const idx_t indices) override;
Function	Queries n feature vectors with specified indexes.
Input	int n: number of vectors to be obtained. *const idx_t indices**: index corresponding to n vectors to be obtained.
Output	*float16_t features: feature vector corresponding to an index. The length is n × dim** (vector dimension).
Return value	APP_ERROR: return status. For details, see Return Code Reference.
Restrictions	indices: The index range of each feature is [0, ntotal). ntotal can be obtained through the GetNTotal API. n: The value range is [0, capacity]. features and indices must be non-null pointers and their lengths must meet the requirements. Otherwise, an out-of-bounds read/write error may occur, causing program breakdown.
