parameters 0.28.1

Changes

• Methods for glmmTMB objects (ci(), model_parameters(), standard_error())
  now support the vcov argument to compute robust standard errors.

• model_parameters() for marginaleffects objects is now more robust in
  detecting Bayesian models.

• Modified code base to address changes in the marginaleffects package from
  version 0.29.0 onwards.

Bug fixes

• Fixed issue with equivalence_test() for models of class glmmTMB with
  beta_family().

• exponentiate = TRUE in model_parameters() did not exponentiate location
  and scale parameters for models from package ordinal.
