Fix install

[physics-sec]

Hello! First of all, thank you for your amazing work, combining cobalt strike with python sounds insanely powerful.

This is a fix to the installation issue described here: https://github.com/cobbr/SharpGen/issues/6

To install, as described in the readme, just run:

sudo python3 setup.py install

At the end we can see that it installs properly:

Installed /usr/lib/python3.9/site-packages/pycobalt-1.2.0-py3.9.egg
Processing dependencies for pycobalt==1.2.0
Finished processing dependencies for pycobalt==1.2.0

I ran the 'example-alias' command and it seems to be working fine.
