Convert .npy files in a directory to images (.png)
I have around 20,000 `.npy` files in a directory. That main directory has no subfolders:-

```py
Main_dir
   |
   |--1.npy
   |--2.npy
   |--3.npy
   |--........
```
The absolute file paths are stored in a list named `paths`. 

What is the fastest and most efficient method (time and memory-wise) to convert all these `.npy` files to image (`.png` preferable)?

I don't care if the solution would be `pythonic` or in `bash`.
