Sophisticated Backpacks Slot Upgrades

Early version so bugs are expected.

I made this mod only for myself originally but thought others might want more backpack storage too. Especially with big modpacks.

I have not tested this mods compatibility at all except for JEI which obviously works with it.

Feel free to report any glitches or incompatibilities you find but dont expect them to be fixed instantly! Have fun (;

(The only dependencies are sophisticated core and sophisticated backpacks. No additional mods needed.)
