Add the quiet option available

[LuisLauM]

Your package is excelent and very useful. I would just suggest to leave the quiet option available for the user in order not to fill out the console with multiple messages when on an intensive routine of downloadings.

Hi @LuisLauM,

Thank you for your feed back. Note that quiet was never an option in this package. I'm not sure whether I want to add additional arguments, as they can already be overwhelming. I'll leave this comment open to see if anyone else feels the same as you. Note that you can already suppress messages using suppressMessages (see https://adv-r.hadley.nz/conditions.html).
