add load file option

Hi @raverrr .

its a very good tool, but can you add a load file option like plution -l urls.txt

Thanks

Hi marz.
Plution reads stdin. So you could do this:
plution < file.txt

I don't plan on expanding functionality for this.
If you wanted to do it yourself, you could add the read, a new flag, and use the containsEmpty function. Should be pretty straight forward
