Customize Phantom Spawning & Attacking

Lets you customize which players phantoms spawn on and which players phantoms attack using a config file.

If the config file doesn't exist, the mod will create the default one, which behaves like vanilla.
There is the commmand /reloadphantomconfig to reload the config of the mod from the file.
In config/customize-phantom-spawning-and-attacking.json:
First entry: @everyone or @no one
then you can say it as:
"everyone, except A, B, & C" (exclude A, B, & C)
or "no one, except/but A, B, & C" (include A, B, & C)
Example:

{
  "attack": [
    "@no one",
    "IAmTheOnlyPersonThatWillBeAttacked"
  ],
  "spawn": [
    "@everyone",
    "IAmTheOnlyPersonThatPhantomsWillNOTSpawnOn"
  ]
}
