23.04.03. Added storage, increased Knox, adjusted difficulty, extracted langu

1. A storage have been added. Now you don't have to leave items on the ground. The storage will also be placed in boss raids, so you won't run out of ammo in boss fights.

2. Knox has become more powerful: not only does his Concentration effect now provide 100% Critical, but it also gives him an additional +1 Penetration. And his hunting dog, Max, can now join him. Max is a longtime hunting companion of Knox's, and he'll assist him when he attacks, causing zombies around him to take 20% more damage.

3. We've gotten some feedback that the 'Very difficulty' was too easy, so we've made some significant changes to the difficulty. The 'Very difficulty' should now be a satisfying difficulty for those looking for a challenge.

4. the language file has been extracted to output.json, so users can correct any incorrect translations. Thank you.

5. Added a armor slot. Previously, armor had to compete with other accessories. But now that enemies are getting stronger. We've added a slot for armor, which will allow you to spend resources to withstand attacks from more powerful enemies.
