Readme.md import example

[zansity]

Hello,

From the example to import the module (from pynvml import *) should be import pynvml or to import a specific function or subclass for best Python coding practices.

The phrase from module import * can cause namespace collisions within people's code and should be avoided whenever it can.

Agree that import * should be discouraged. If I understand correctly, the "example" actually predates this repository. Are you interested in submitting a PR to improve this?

Of course! Thank you.
