Resin Bundle Pins

# Resin Bundle Pins A simple add-on to [Bundle Pins](https://modrinth.com/mod/bundle-pins) that adds support for resin pins to 1.21.1 with resin from [Vanilla Backport](https://modrinth.com/mod/vanillabackport). --- The following extra files are also available: - _assets_ : **resourcepack** for the client to display the pin - _data_ : **datapack** for the server to register & craft the pin - _merged_ : **resourcepack & datapack** (_assets_ & _data_) unified in one file, can be used interchangeably by client & server, but still needs to be on both!
