multiple script edition/creation

[manuvector]

Hey there, really cool project.
Since the sgpt --code "prompt" > script.py works so well, I implemented the option to modify and or create multiple scripts with a single prompt. It works as follows:

Existing scripts:

example/add.py
def add(x,y):
   return x+y

example/calculate.py
from add import add

def calculate(x,y):
 result = add(x,y)*add(x,y)
 return result

print(calculate(2,3))

Run sgpt with --multiscript-code option

sgpt --multiscript-code --project-path example/ "can you extract the multiplication in calculate as an import from an external script"

Resulting modified and created scripts:

example/add.py
def add(x,y):
   return x+y

example/calculate.py
from add import add
from multiply import multiply

def calculate(x, y):
    result = multiply(add(x, y), add(x, y))
    return result

print(calculate(2, 3))

example/multiply.py
def multiply(x, y):
    return x * y(transformers)

if you agree that this is a useful feature I create a pull request.
