DnT Nether Fortress Overhaul

## Dungeons and Taverns Nether Fortress Overhaul v3 ##
- Overhauled the Nether Fortress from the ground up
  - none of the v2.7 parts are used because of that
  - meaning this will no longer cause issues with the Nether Keep from Dungeons and Taverns
- The Lava well hours has been fully overhauled but still has a guaranteed blaze spawner but also 3 additional vanilla fortress chests
- The Bridge has been fully overhauled to be much more brutalist, slim bust still keeps its inside part
  - Every bridge piece has a 1/4 chance to spawn a chest with the vanilla fortress loot
  - Every Bridge Intersection part (that's the part between 2 crossroads as example, they are always straight) has a 1/6 chance to spawn a Blaze Spawner Tower (if there is space for it)
- The entire Fortress Inside halls part has been overhauled
  - There are 3 types of hallway parts:
    - Slim: those hallway parts have a chance to spawn a vanilla fortress chest or decoration or just nothing at all.
    - Stairs: meaing the stairs part, this one always goes 1 level down. Netherwart stairs and Blaze Stairs, those split the nether fortress hall part to continue on the same level and 2 levels higher
    - Wings: meaning those parts can contain rooms, there are 30 7x4x7 rooms and 11 7x4x15 rooms (includes rooms with blaze spawner and magma cube spawner)
  - Rooms can have chests with the Overhauled Nether Fortress Loot chest. those roll once for the vanilla nether fortress loot to ensure mod compability and then for a custom loot table made for this overhaul
  - Curves cant connect to other curves
  - Wings cant connect to other wings
