[Feature Request] Support for Supplmentaries sacks

[3ncanis]

I noticed Shulker Box Tooltip supports Inmis the backpack mod (not sure if that's intentional but it does) And would love to also be able to preview the sacks added by the Supplementaries mod (https://modrinth.com/mod/supplementaries)

Hi, support for modded containers are usually added by the mods themselves trough the plugin system to keep to mod's size low for player who don't with modded content.

@MehVahdJukaar What do you think about added ShulkerBoxTooltip support for Supplmentaries sacks? If that's okay, could I submit a PR to your repo ?

Yeah feel free to PR!
