Black Market 2-fix

Hi, in this fix of the original Black Market 2, I changed the size of the item icons in the mod interface, because it was very small for me. The author of the original fashion did not answer anything for a month... I hope someone else will benefit from my small update. Everything else remained as it was. original mod: https://mods.factorio.com/mod/BlackMarket2
