Implement a `__main__.py` with the functionality of blinding a SACC file #21

Implement a main function that can be called from the terminal and blinds a SACC file provided by the user.

This is going to be challenging because the build_likelihood() methods read automatically a sacc file.

The firecrown likelihood families demand that .read() method is called instantly and this method actually somehow filters the required data-points/binning/etc.. the likelihood "knows" how to get the theory-vector in the same shape of the (internally) selected data-vector. But there's no way of extracting that information from the likelihood so that it can be applied to an external data-vector, loaded outside the likelihood.

This really complicates things for blinding. The solution found so far would only work for a data-vector that is already being loaded into the firecrown likelihood.

@tilmantroester pointed out that jsonargparse module could be super useful for this!
