fix build error on centos 8

I used python-recaptcha-client in CentOS 7 and noticed it is not available in CentOS 8. I queried the rpm database to retrieve the following:

URL         : https://github.com/redhat-infosec/python-recaptcha
Bug URL     : https://bugz.fedoraproject.org/python-recaptcha-client


Grabbed the source from the github repository and it failts to build on CentOS 8 with the default version of python installed

[nmm@burnout ~]$ rpm -qi platform-python
Name        : platform-python
Version     : 3.6.8
Release     : 23.el8
Architecture: x86_64
Source RPM  : python3-3.6.8-23.el8.src.rpm


Version-Release number of selected component (if applicable): 2.0.1 (latest) from the github repository in URL from CentOS7 python-recaptcha-client information



Steps to Reproduce:
1. unpack source
2. try to install with: python setup.py install --prefix=%{__prefix}


Actual results:
Fails to build with the following output:
byte-compiling build/bdist.linux-x86_64/egg/recaptcha/client/__init__.py to __init__.cpython-36.pyc
byte-compiling build/bdist.linux-x86_64/egg/recaptcha/client/captcha.py to captcha.cpython-36.pyc
  File "build/bdist.linux-x86_64/egg/recaptcha/client/captcha.py", line 141
    except Exception, e:
                    ^
SyntaxError: invalid syntax


Expected results:
Should build

Additional info:
While not sure if that's the correct way to fix it, I did attached a patch which sorted the issue for me. Thanks. If you could make the rpm available for CentOS-8 would be great.
