Provide a way to run functions quietly - without output

[daattali]

I'm calling range_write() in a loop, which results in a lot of repetitive messages in my console

Editing "Untitled spreadsheet"
Writing to sheet "sheet1"
Editing "Untitled spreadsheet"
Writing to sheet "sheet1"
Editing "Untitled spreadsheet"
Writing to sheet "sheet1"

But actually it's a lot more than this. This makes it very difficult to notice if any warnings occured. I can shut it up with suppressMessages(), but that's not a great solution, I think it would be good for googlesheets4 to provide a mechanism to be quiet/non-verbose. I did a search for "verbose" and "quiet" in this codebase and couldn't find any, and I couldn't see anything in the docs or online, so my apologies if it does exist but I wasn't able to find it.
