Option for Spawneggs changing Spawner Type

### The Problem

Hey :)
I already asked 1-2 days ago in discord but I will repeat it here so that it won't get flooded away etc:
Is there the possibility that you can implement the option (either in the general config or in the blacklist-txt for per-world options) to change the behavior on monster-spawners?
So that users can NOT change the spawner types with spawn-eggs but still destroy them with a pickaxe?

Currently I only can set up in the blacklist the attribute "on-use=deny" but this prevents also the mining of the spawners.

### A Solution

- general config option like "change-spawner-type-with-eggs: true /false "
- or new option for the blacklist-txt for per-world settings

### Alternatives

If that isn't as easy maybe an own region-flag?`something like "spawner-changetype" (allow/deny)

### Anything Else?

Hope it is possible in any way, but this current way is a bit blocking 😅

Thanks in advance 🫂
