[Docs] Steps to run PulseCOT

[CoryFoy]

For those trying to get started, here's the steps I took:

1. You have to get your PulsePoint Agency ID. The easiest way I found to do that was to go to web.pulsepoint.com, search for an agency, and then look at the network inspector in your browser to see what agency_id it requests

2. I changed line 56 in setup.py from package_data= to license_package_data= to get around the name confliction warning

3. Because I wanted this sent to a TAK server, I created a user on my TAK server and copied over the .pem and .key file into the same directory as I was running pulsecot. Note that you have to make sure you remove the passphrase or you'll get a prompt for the password

4. PulseCOT wants the config.ini file to look basically like this. You need to replace AGENCY_ID, takserver and clientcert with what yours actually are:

[pulsecot]
AGENCY_IDS=AGENCY_ID
COT_URL=tls://takserver:8089
PYTAK_TLS_CLIENT_CERT=clientcert.pem
PYTAK_TLS_CLIENT_KEY=clientcert.key
PYTAK_TLS_DONT_VERIFY=1

(Note I have the above without the truststore cert, so I have don't verify enabled. You probably want to add in the appropriate configuration)

And viola! I was able to run pulsecot -c config.ini and see events populate locally and on my TAK server.
