Disable Portal Checks

Disable unnecessary portal checks that cause lag.

NOTE: I have verified the mod works for versions 1.19.3 – 26.3. It is simple enough that it will _most likely_ work in future versions, but it may take me a while to get around to testing it and updating the versions. If you want to force it to work in an untested version, you can use Fabric’s Overriden Dependencies feature to do so at your own risk. If it does not work (the game should not compile if it doesn’t), then dm @Soronto on discord.

In pre-1.19.3, nether portals would send mobs through without regard for collisions on the other side. This can have the adverse effect of causing large mobs to suffocate if they spawn inside a suffocating block on the other side of the portal.

Since 1.19.3, Mojang implemented an algorithm to check if a mob will suffocate when going through in the default position, and will attempt to locate a “clear” position if it will. However, this is very computationally expensive and can significantly increase lag when dealing with large numbers of mobs being transported through portals.

This mod will eliminate the check and bring back pre-1.19.3 portal behavior. This will obviously return the edgecase where a mob will suffocate, but especially for portal-based farms, this mod will also greatly reduce the MSPT cost.
