Cold-blooded (player trait)

This datapack is fairly simple but I figured I'd put it here anyway and update it later if I add something to it.
The idea is that if you want to play a character that's a lizard or a bug or something that gets slow in the cold, you can use this!

Tagged players get speed if:
-they're in hot biomes (Nether)
-they're in warm biomes in high light levels (deserts, badlands, savannah)

and slowness if:
-they're in frozen biomes (ice/snow, the End)
-they're in cold biomes in low light levels (mountains, tundra, taiga, etc)


To add this trait to a player, use:/tag [username] add coldblooded
I might change the predicates later or make it so the speed/slowness takes effect after a certain amount of time; if I do that, I'll update the pack!
I do intend to update it for the new snowy biomes once 1.17 comes out, too.

This is my first datapack so lemme know if you have any suggestions or advice-
Also thanks to HoboMaggot for answering my questions/helping me figure out what I'm doing!
