Nether Fog in Overworld

### Description

Since the NETHER has dense fog, we should be able to use the nether fog in the overworld. We can do this by intercepting outgoing packets and setting the dimension type to nether.

### Configuration

In config, it can be stored like this, but it should only be edited by command.

```yaml
# Allows you to change the dimension.
# OVERWORLD has a sun/moon cycle
# NETHER has dense fog reducing visibility
# THE_END has "star-filled" sky
Dimensions:
- world OVERWORLD
- world_nether NETHER
- world_the_end THE_END
```
