Put prettify in separate package?

[afbjorklund]

Hi, thank you for this interesting tool!

Would it be possible to put the Prettify function into a separate package for use as a library?

Now when you import gotestdox, you also get all the command dependencies like "color"...

Was testing it with go-test-report
