驮运能力 Pack ability for all animals

创建商队时，所有动物可以帮忙驮运物品,搬运重量与体型大小相关
All animals can pack goods when forming caravan. Packing weight is based on their size.

注意：
由于官方没有提供原版贴图，部分动物装载物品后会出现颜色变白，卸载物品后颜色恢复正常。
其它mod新增动物驮运时会出现贴图错误,但不影响驮运功能，将本mod排在这些mod后面可以关闭驮运。

Cation:
Some animals will become white after load-up goods due to lacking offical texture. They'll return to original color after load-off goods.
Animals added by other mods will cause texture error when packing things, however they can still packing things.List this mod after these mods can avoid this error.
