Datapack Config file

Like mods, with config folder in .miencraft with .toml files for mods configs, BUT for Datapacks ! With a .toml file or .json or... in the Datapack file (in the same place as the pack.mcmeta file)

And there could have a sub execute command, or a command, or a system like macros puting for example $[config_option_name] instead of $(macro_name) but to put the value of the option.

The execute command could have another sub command with if : if config_option $[config_option_name] = (and we put a value like true or false, or string, or number...)

Because it's too long to create a tellraw command just to config a Datapack, like this, admins can just modifiy the config file to change configs (but we can also make a tellraw for configs that changes values in the config file maybe ?)
