Lack of reporting on versions ^3

[Red-CF]

Hi, I've been using mutmut for quite some time, manly the version 2.4.5, today I upgraded to ^3.3.0 version and to my surprise I couldn't generate the reports in XML and HTML like I could in later versions.

These are the command that i've been using to generate reports:

• mutmut junitxml > mutant_results.xml
• mutmut html

I wanted to ask why there's no support for this actions anymore, and also if it could be added to the latter versions.

Best regards, and thanks in advance :).
