Change type of $conf from SimpleObject to class to enable types properties

[BePo65]

Today the $conf property of EsDay is a Record<string, SimpleType. This enables e.g. plugins to add arbitrary properties to this object that can be used by the plugin.

If we changed the type of $conf to the instance of a class (to be created), a plugin can use module augmentation to add properties to $conf. This way the new properties do not have to be of union type SimpleType as today, but can be of a specific simple type (e.g. boolean). This would enable type checking by the typescript compiler.

Another positive effect would be that we get an automatic documentation of the configuration parameters of a plugin.

The used class should have a clone method to replace the destructuring command used with the current implementation.
This could be implemented like this (based on a github gist:

clone() {
  return Object.assign(
    Object.create(
      // Set the prototype of the new object to the prototype of the instance.
      // Used to allow new object behave like class instance.
      Object.getPrototypeOf(this)
    ),
    this
  )
}

I will try this.

Its only been today that I came across the arg_1 properties of $conf.

An idea to implement this in a conf class, we could perhaps be:

class conf {
  args: Record<string, SimpleType>
  clone() {
    :
  }
}

This way, we only had to replace e.g. args_1 with args.args_1 - but tht is just an idea 😄.
