The zid.properties file was made in an attempt to apply the potion effect textures to
potions given using the /give command with the CustomPotionEffects nbt. I was unable to
figure out how to identify the effect ids from eachother but was able to apply one
unique texture layer for any potion summoned with a custom potion effect.

Through various testing and much confusion (I'm not very experienced with Minecraft's
syntax, my Java classes didn't prepare me for this [for some reason]) I found that
placing the zid file with any CustomPotionEffects id number, any amount of Duration, and
any amount of Amplifier in the strong folder specifically would apply the texture to the
correct given potions.

I do not understand why, just that it works and I am too confused at the time of
writing this to figure out a better solution. This property file is thus replicated for
the splash and lingering potions, and the arrows if I end up doing those as well.

[Fun fact, the reason this property file is called "zid" is because it used to be
called id22, as I assumed I would have to make a file for each effect id, and then
learned that the texture I applied would apply to every effect whose name came after
"id" alphabetically, for SOME reason. Hence my appending "z" to the front.]
