support multiple files, including shell regular expressions

[khamer]

This is a quick implementation for #2 - I've made it support variadic file/directory names. The summary isn't perfect, but I think we'd need to rework the async/await stuff with cipher() for that, and to be honest, I'm not sure why you're using async/await there.

This will work with shell regular expressions; so you can run commands like

$ warshield encrypt *.secret

$ warshield decrypt {foo,bar}files

$ warshield encrypt $HOME/secret-project-*

Hey 👋 First of all, thanks for showing interest to WarShield and for contributing!

You got a good idea for multiple files, I take it for a real functionality.

However there is an issue, cipher() is a only-one use function because it outputs different things that are supposed to be write only one time (like Crawling directories... Done!).
To fix this issue, we will need to work with the cipher() function and not to loop over all requested files in gate().

gate() is only for password asking, only cipher() should do real operations.
I need to rework the architecture tho 😄

Fix those things and I will be very happy to merge your contributions!

Closed because of architecture reworking - this PR will be reworked tho
