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

Correlations and measurement errors in identification:
...
1) Filter out measurement errors with error message that suggests to explicitly write measurement errors in model definition
2) allow identification checks with correlations, by switching to numerical derivatives

Fixed prior bounds (according to the doc in master branch).
...
* 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.

Bugfixes and improvements related to method 3 of lyapunov_symm.m
...
- the function was called with the wrong input argument for this case (Q instead of R*Q*R'), crashing with incompatible matrix dimensions
- the persistent variable X was not updated when the size of it changed, leading to crashes when estimation is followed by calls to DsgeSmoother.m where the state-space is different
- Also eliminates the printed output in lyapunov_symm.m that could not be turned off and clutters estimation

substracted to fval (likelihood-lnprior) at the end of dsge_likelihood. The arguments of this routine are: M_,
oo_, options_, dataset_ and dataset_info. Routines for writing <MOD_FILE_NAME>_prior_restrictions.m will be
provided later.
