This addresses https://github.com/incu6us/goimports-reviser/issues/96

• iterate over the list of remaining arguments treating each as an origin path

• defer printing deprecation warnings until after all paths are processed

• print deprecation warnings to stderr, not stdout

@incu6us I've updated this against current upstream/master and fixed the conflict

Is the codecov test advisory, or are you asking for test coverage going forward? There's no current test set for main.go, but I suppose we could make one...

@incu6us I've updated this against current upstream/master and fixed the conflict

@n-oden could you update it once again?

[n-oden]

@incu6us @ccoVeille addressed the comments, rebased on current upstream/master, and while I was at it spotted another issue: the call to helper.DetermineProjectName needed to be moved inside the loop over originPaths since different paths might have different project names.

[ccoVeille]

Great. Let's waif for @incu6us feedbacks then

[incu6us]

thanks @n-oden for your help. I have no any additional comments. agree with @ccoVeille about his comments to make some things more readable and simpler.

[n-oden]

Thanks to all of you for getting my PRs merged and released!
