Allow for non-interactive use

It took me a while to figure out why my notebook was not executing properly: a cell was stuck showing an "stdin" input box. It turns out that PalmerPenguins.load() was waiting for user input to download the dataset.

Is this necessary? I expected the data to be downloaded silently. It seems to me that installing the PalmerPenguins package says clearly that I want to install the data. Asking for confirmation during the program executing seems like needless friction...

For context, I'm preparing a script for PackageCompiler to make a sysimage. I wanted to include a tutorial that uses the PalmerPenguins data as typical code that should be precompiled. The script should be executable in a new Julia installation without user input, but I'm not sure how to do that given this confirmation prompt.

Using ENV["DATADEPS_ALWAYS_ACCEPT"] = true prior to loading the dataset may work.
