Problems using synthesis mode

[Hypnus1803]

Hi Andrés,

I updated recently hazel2, and i got a new issue running synthesis mode, for example, if I try to run the example in https://aasensio.github.io/hazel2/notebooks/boundary_conditions.html#How-to-deal-with-boundary-conditions i got the next error:

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

    259             self.use_analytical_RF = True
    260             if (self.verbose >= 1):

AttributeError: 'Model' object has no attribute 'use_analytical_RF_if_possible'
