Sslyze v3.0.8, Error when running --sslv2 for a website

[r0oth3x49]

Describe the bug
I tried to run the latest sslyze against website from ssllabs ib.turkmenturkbank.com and it throws an exception while scanning for SSLv2 ciphers.

To Reproduce
Steps to reproduce the behavior:

1. Installed SSLyze using pip the latest version 3.0.8
2. sslyze ib.turkmenturkbank.com --sslv2
3. See error

Expected behavior
Shouldn't through an exception instead it should show either it is supported or not.

Python environment (please complete the following information):

• Ubuntu 20.04 LTS
• Python 3.8.2
• SSLyze v3.0.8

• I have also tested with testssl.sh and ssllabs as usual both were fine.
