added custom driver support in scrape function

[mnamegaurav]

I am using Scweet with the flask backend to scrape the data, but facing few problems while deploying because of selenium. While searching for alternative ways, I figured out that we can use Docker to containerize the whole application and run the selenium service through docker image.

While implementing this, I found that there is no way to define or pass custom driver with scrape function. I have implemented this feature on my own, but would like to merge this in the library.

Would be really useful in other methods such as get_users_followers, get_users_following as well
