Implement wright map

[p-gw]

We should add wrightmap to the package, a common plot for item response models.

https://www.wrightmap.org/ implements Wright maps for a variety of models in R.

[p-gw]

Since Wright maps are based on parameter estimates of the model, we need a way to fetch them via the AbstractItemResponseModels.jl API.
