v3.0.3

nlmixr2est 3.0.3

• Moved data check for covariates and required data items to a
  pre-processing step. This fixes #499. Each method that needs to
  have a covariate check needs to have a property covPresent. For
  example to apply the covariate data check to the focei method you
  need attr(nlmixr2Est.focei, "covPresent") <- TRUE.

• Bug fix for non-mu referenced etas when combined with mu referenced
  covariate values. (See #498)

• Changed option for "saem" to have literalFix=FALSE. This makes
  mu-referencing work better when fixing a population value.

What's Changed

• Fix saem translation for non-mu referenced saem by @mattfidler in #500
• Move covariate check to a hook instead by @mattfidler in #501
