Seed for random functions

[sadrasabouri]

Description

Normally, when you wanted to use the random generative mode, you would need to set a random seed out of the object initialization:

>>> from samila import GenerativeImage
>>> import random
>>> random.seed(0)
>>> g = GenerativeImage()

Instead of this, we can have a parameter that controls the random function generation.

Steps/Code to Reproduce

>>> from samila import GenerativeImage
>>> g = GenerativeImage(func_seed=0)
