create target should accept directory for --seed arg

Currently, the user has 2 to create a .tar.gz archive of the corpus in order to submit it with --seed arg.

To save this step --seed arg should also take a directory name. If it's a directory, it does the creating of .tar.gz itself.

Also, should validate that there are no subdirectories (which is probably a mistake) and that there is at least 1 file.

Agree. BTW currently the workflow is usually creating the target via dashboard.

Understood, but looking from the perspective of submitting instructions to projects about how to integrate their projects with fuzzit, I would like to script as much as possible, so they can re-create the necessary steps easily.

Less they have to use the UI, the better.
