Support encoding.Text(Unm|M)arshaler #310

Closed kyoh86 closed 4 years ago

I'm fed up with implementing "MarhsalXXX", "Stringer", etc, etc... kingpin requires "Value" interface to parse string even though there's cool interface "encoding.TextUnmarshaler".

BTW, the Value interface is adopted from the stdlib's flag package, so it's not something specific to Kingpin :)
