[Request] Provide option to install all available variants of a font

[warslett]

99% of the time when I install a font I want to install all available variants of that font. By default the plugin only installs the default normal font. If I want the other variants I have to list them all out one by one in the config and first I need to look up what they are. This is a very manual process. It would be useful if you could just specify to install all available variants for a family or better still make this default behaviour. Then you only specify specific variants if you want to restrict which variants get downloaded.
