Remove argparse dependency

[sidju]

Since argparse has been built into python 3 since version 3.2, is it maybe time to remove that as a dependency?

As it stands, at least archlinux is starting to consider removing python-argparse from repos. It would be nice if my packaging of this application could survive that transition.

Link that mentions deprecation of python-argparse package: https://bugs.archlinux.org/task/78484 Link where I have been specifically asked to remove the dependency: https://aur.archlinux.org/packages/gitgud-git#comment-914581

( I have tested the suggested workaround package, but due to this application verifying the presence of declared dependencies at startup it doesn't work. )
