Fix go module name

[ixdy]

It looks like there was a typo in the go module name introduced in #19:

$ go get -u github.com/octago/sflags
go: github.com/octago/sflags upgrade => v0.3.0                                          
go get: github.com/octago/sflags@v0.3.0: parsing go.mod:                                                                                                                        
        module declares its path as: github.com/sflags                                                                                                                          
                but was required as: github.com/octago/sflags     

Note that we'll need to tag a new version after merging this PR.

@ixdy Thank you.

I need to check what needs to be fixed for Travis-CI tests.

I think something may have changed about formatting in go1.15. When I run the tests locally (against go1.15.8):

whereas the tests all pass against go1.14.

[ixdy]

Yeah, golang/go@201cb04 caused the new failures. Thinking about how to best fix this now...

[ixdy]

(one option would be to test only against go1.15+ and update the test cases, especially given that go1.14 is likely going to EOL soon, though I'm not sure if that's something you're comfortable with.)

[m0sth8]

@ixdy sorry, I have some issues with internet because of the weather and snow. Hope I'll be able to take a closer look next week.
