Add simple command-line interface

[merwok]

Hello! Thanks for this lib, it’s really useful to generate unique IDs painlessly.

Often I want to generate a bunch of values, for example to define object IDs in test fixtures. It’s easy enough to open a Python shell to do that, but would be even easier with a command-line interface 🙂

Simplest version:

# add shortuuid/__main__.py
from .main import uuid

if __name__ == "__main__":
    print(uuid())

$ python -m shortuuid

Featureful version: add params to control length [*] and number of IDs to generate.

*: I’m not sure if this should use ShortUUID.random or uuid+truncate

Hmm, that's a good idea. I would not be opposed to it, would you care to open a PR?

Yes! Simple or full version?

Probably the simple version first, and we can take it from there!
