Pufferfish with very high PuffState value can freeze the client

Relates to MC-202760 and MC-220698

Pufferfish can be summoned with very high PuffState value (which is normally between 0 and 2.) Doing so will cause the client to freeze while rendering its shadows. In my setup, the value of 10000 caused it to freeze for 2.5 minutes before it died due to suffocation.

Steps to reproduce

1. Enable entity shadows
2. Run /summon pufferfish ~ ~ ~ {PuffState:10000}
3. Client freezes
