Summary

Mods "[DinoMod] sauropods out of the water"

Purpose of change

fix #71220

Describe the solution

Takes advantage of new GROUP_STREAM group to move water loving sauropods out of deep rivers while keeping them connected to the river system. This should produce much more a much more realistic experience.
Renames RIVER predator groups and moves them to STREAM also
Now the only things in the GROUP_RIVER from DinoMod either swim or fly

Additional context

Thanks to the many players who have requested this fix over the years, and to @Light-Wave for finally creating the infrastructure to make it work

You have a nested mongroup error.

(continued from above) ERROR : src/mongroup.cpp:612 [static void MonsterGroupManager::check_group_definitions()] monster group GROUP_DINOSAUR contains unknown subgroup GROUP_DINOSAUR_PREDATOR_RIVER

Thanks, I was having trouble interpreting that error

Oh wow thanks, I think I opened this like 3 times over the last 2 years? every time it became STALE.

They told me on the Discord that it was normal for those dinos to be there in the middle of an open sea/lake... like yeah no man there's no sense to that...

I mean of course in streams and somehow smallish lakes but I kept finding them when just going around in my motorboat in the middle of the open sea, like 2 or 3 kms in and that made no sense at all

So yeah thanks for that, I would understnd absolutely it those were marine dinos like the one that eats the Indominus Rex in that Jurassic Park movie, or some sort of Kraken beast but yeah no river dinos go into open sea to "chill"

Thanks a lot, really, 10/10 finally. <3
