Creates a new instance of the `results` R6 class. This class is designed to store various outputs from `iglm` model estimation and simulation. Users typically do not need to call this constructor directly; it is used internally by the `iglm_object`.
Arguments
- size_coef
(integer) The number of non-degrees coefficients the object should be initialized to accommodate.
- size_coef_degrees
(integer) The number of degrees coefficients the object should be initialized to accommodate.
- file
(character or NULL) Optional file path to load a previously saved `results` object. If provided, the object will be initialized by loading from this file.
