Import cli only when click is available

[Tobi-De]

This is package init.py code

from refreshcss.cli import cli
from refreshcss.html.site import DjangoSite, PathSite
from refreshcss.main import RefreshCSS

__all__ = ["RefreshCSS", "DjangoSite", "PathSite"]


if __name__ == "__main__":
    cli()

I'm proposing changing it to something like this

from refreshcss.html.site import DjangoSite, PathSite
from refreshcss.main import RefreshCSS

__all__ = ["RefreshCSS", "DjangoSite", "PathSite"]

try:
	import click
except ImportError:
	pass
else:
	from refreshcss.cli import cli
	
	if __name__ == "__main__":
		    cli()

I have a django project where I'm using refresh as a django-compressor filter, click is not present but the compress command fails with the message module not found click

so fresh, so clean.

I swear you always find great package names 🤣 , I'm so jealous

Oh jeez, it was definitely my intention to only try to import click when needed. I'll approve your PR now!

Merged and published a new version with this change. Thanks for the PR!
