helper/copy CopyDir was used heavily in tests. It differes from internal/copydir in a few ways, the main one being that it creates the dst directory while the internal version expected the dst to exist (there are other differences, which is why I did not just switch tests to using internal's CopyDir). I moved the CopyDir func from helper/copy into command_test.go; I could also have moved it into internal/copy and named it something like CreateDirAndCopy so if that seems like a better option please let me know. helper/copy/CopyFile was used in a couple of spots so I moved it into internal, at which point I thought it made more sense to rename the package copy (instead of copydir). There's also a `go mod tidy` included.
