trigger-raids flag

### The Problem

In our small survival server, we have a community trader hall right at our spawn point. However, with the large amount of foot traffic spawn gets, people occasionally forget that they have the Bad Omen effect and trigger a raid at spawn, which isn't ideal.

### A Solution

We already have a region around spawn to prevent explosions from damaging the work in the area. It'd be nice if there was a trigger-raids flag that we could toggle off in this region, so raids could no longer occur within this area.

This would solve problem we're having at spawn without breaking player's raid farms in other parts of the server or having to modify our design to supply cows as a reminder to remove the effect.

### Alternatives

From the research I've done, I couldn't find an alternative method of achieving this with the plugin itself.

### Anything Else?
