Plots cateye or dot plots for item parameters

plot_itemparameter(
  model,
  pars,
  style,
  items = c(1, 5),
  thresholds = c(0.2, 2),
  alphacut = c(0.2, 0.3, 2),
  betacut = c(-2, 2)
)

`model`	birtmsfit object
`pars`	character; either 'slope', 'easyness', 'delta', 'beta', 'difficulty' or 'pseudoguess'
`style`	character; either "halfeye" or "dots"
`items`	integer vector of length 2; indicates first and last item to plot the parameter distributions for
`thresholds`	double vector of length 2; crops the plot horizontally
`alphacut`	double vector of length 3;
`betacut`	double vector of length 2;
