[util] Add numpy file reader

[util] Add numpy file reader

In deep learning data feeding, there are often tasks that involve reading and processing numpy (.npy) files.

Therefore, it would be much more convenient to develop by entering the file name and returning the data in a vector instead of manually writing code to read it every time.

Function Signature
```
void read_npy_file(const char *file_path, std::vector<int> &dims,
                   std::vector<float> &values);
```

**Self evaluation:**
1. Build test:	 [X]Passed [ ]Failed [ ]Skipped
2. Run test:	 [X]Passed [ ]Failed [ ]Skipped
