[REQUEST] - Extend Trading to Group Sheets

[Zimnior12]

Is your feature request related to a problem? Please describe.
Currently D&D Game System doesn't support transferring items via drag and drop. It just copies them. This makes managing group sheet hard for player since all of their items are getting duplicated when they move their stuff between inventories.

Describe the solution you'd like
Trading could be expanded to cover group sheets so players can automatically trade with Group Sheet inventory, where they can manage it later without duplicating items.

Describe alternatives you've considered
Tried a few other modules such as Droplet and dnd5e scriptlets. Sadly both are not working correctly and I already reported issues there. Still would like to see this module expand on this aspect.

Additional context
Nothing really to add here.
