[MFPS] Shop Bundle addon [UNRELEASED]

DESCRIPTION
This asset introduces a functionality for creating bundles of in-game items. These bundles allow multiple items to be grouped together and sold as a single package. The concept is similar to what you find in contemporary games like Call of Duty, where a bundle might include a character skin, weapon skins, an emblem, and a calling card. When a player buys such a bundle, they gain access to all the items included. Custom bundles can also be easily created using this asset.
