Add extended reactions for different TL/User Groups

Curently reactions can be added using the plug-in by setting discourse_reactions_enabled_reactions to the list of emojis you want as reactions separated by | eg: open_mouth|cry|angry

Here’s my humble request to ask if we could add 2 more settings:

discourse_reactions_enabled_reactions_privileged

to define extended reactions available to a privileged group and:

discourse_reactions_enabled_reactions_privileged_groups

to define the groups with access to these extra reactions.

Actually it would be nice to be able to define multiple groups and reaction sets, but maybe the UI would be difficult to implement.
