Wolves and Spiders on Earth and Mars

Updated for planet definition changes in update 1.207 Apex Survival. 

This is a test of adding both Wolf and Spider spawns to the Earthlike and Mars planets.

Wolves and Spiders must be enabled in the advanced world settings, and Experimental mode must be enabled in general settings.

Overrides PlanetGeneratorDefinitions.sbc / AnimalSpawnInfo for the Earthlike and Mars planets only.

The Earthlike Wolf spawn rates have been modified as follows:

Daytime:

- SpawnDelayMin: 30,000 (from 60,000 [60,000 in ms = 1 minute])
- SpawnDelayMax: 1,800,000 (from 3,600,000)
- SpawnDistMin: 100 (default)
- SpawnDistanceMax: 200 (from 400)
- WaveCountMin: 2 (from 1)
- WaveCountMax: 8 (from 4)

Nighttime:

- SpawnDelayMin: 30,000 (from 60,000)
- SpawnDelayMax: 900,000 (from 1,800,000)
- SpawnDistMin: 75 (from 100)
- SpawnDistanceMax: 150 (from 300)
- WaveCountMin: 4 (from 2)
- WaveCountMax: 16 (from 8)

The 3 Spider types have been added to the spawn type pool for both planets, and added 2 additional Wolf entries, so spawns should be an even chance of being Wolf or Spider.

Should work with NPC character replacers like Sektan's Zombie replacer: https://mod.io/g/spaceengineers/m/s-zombie-replace-wolves-v1 and https://mod.io/g/spaceengineers/m/s-zombie-replace-sabiroids-v1 (remember: only use one replacer per type, so one Wolf replacer and one Spider replacer).
