Request: 'cover' subcommand to run Devel::Cover

[cxw42]

I like to check the coverage on my modules using Devel::Cover. Presently, I do that by:

• minil build
• cp Dist-Name-0.1/Build.PL .
• perl Build.PL && ./Build
• cover -test

Would you be willing to add (or accept a PR for) a cover subcommand that would automate that process? I think it would probably be the same as minil test, except that the final command would be cover -test instead of ./Build test. Thank you for considering this request!
