v2.5.4

• New function renameGear() to rename gears in a MizerParams object, similar
  to renameSpecies().
• addSpecies() now proceeds with a warning instead of an error when species
  growth stops after maturity (#315).
• matchBiomasses() and matchNumbers() now provide more informative error
  messages.
• plotDiet() now restricts the plot to size ranges with meaningful biomass
  density (#317).
• The wlim and ylim arguments in plotting functions now set the actual axis
  limits instead of just zooming (#320).
• The legend in plotlyFeedingLevel() is improved when critical feeding level
  is included.
• species and gears columns are now never factors, so no longer need to
  call as.character() so often.
• validParams() also calls validGearParams().
• validParams() checks that w_min is valid for all species and increases it
  if necessary.
• validSpeciesParams() now also sets default for p to be equal to n.
• species_params<-() and given_species_params<-() now check that species
  names match.
• The params argument in l2w() and w2l() has been renamed to species_params
  to follow mizer's convention that params refers to a MizerParams object.

Bug fixes

• animateSpectra() now uses consistent colours and preserves colour identity
  across frames (#321).
• getReproductionProportion() no longer returns incorrect proportions > 1 (#299)
• setResource() now correctly applies the w_pp_cutoff parameter to the
  carrying capacity and initial resource abundance when changed without
  providing resource_capacity(#306).
• Predation kernels are now truncated as documented.
• given_species_params() no longer makes unwanted changes to the species
  parameters.
• steadySingleSpecies() no longer changes time_modified.
