Add option to replace import * names with mod.name

[asmeurer]

For example, replace

from numpy import *

def sin_cos(x):
    sin(cos(array(x)))

with

import numpy as np

def sin_cos(x):
    np.sin(np.cos(np.array(x)))

I'm not sure what the interface should look like.

Please add this! Importing objects directly into global scope makes intellisense unusably slow for certain projects

Edit: could be a simple cmd line argument --import-module-instead-of-modules-contents .

Personally I dont use the as syntax a lot, so I dont really have a need for it, but I guess one could also do something like --import-as="numpy as np, taichi as ti"
