Add requirements in README.md

I used raspberry pi 3. I tried to run this script but I needed to install python-requests.

$python joomlascan.py

Traceback (most recent call last): File "joomlascan.py", line 4, in <module> import requests ImportError: No module named requests After install python-requests I solved my problem.

If you are using python 3, you need to install

pip3 install requests
