To refactor multiple methods for Feols to work for both a direct numpy API and the feols and fepois interfaces,
the model needs to know if it can assume information stored when calling feols / fepois - as e.g. model formulas - or not. See #464 for more context.
To do
Therefore, create a model attribute _fml_api_call and set it to True if feols / fepois are called, False otherwise.
Pass this flag to Feols() so that it is available in all methods for Feols.
