Fix bug in dsge_likelihood.m where diagonal of measurement error covariance matrix was not correctly read out

This is a prerequisite for the univariate filter that operates along a vector for H instead of along the diagonal. Because of this, the likelihood in the presence of measurement error was wrong

* Second and third positional arguments after the name of the
estimated parameter in the estimated_params block are only
considered in the optimization stage (not in the MCMC)
* Do not store bounds in bayestopt_, because bounds do not always
reflect restrictions implied by prior shapes.
* prior_bounds routine returns a structure (with fields lb and ub)
instead of a matrix.
