kerberos brute: 'generator' object is not subscriptable

Trying to brute-force usernames currently results in an error:

Wow, I believe you're the only person used that feature in years. Thanks for the issue, it will be fixed in the next release!

For anyone who is getting the above errors, specifically with trying to use the kerberos function, just copy out the code into a text editor of choice or vim, and find the kerberoas spn roast function and add the following above the 'kdomain = targets[0].domain: targets = list(targets)

This will fix the issue. I'm assuming a similar fix will also work for the brute function of the tool.
