inlabru 2.10.1

Feature updates

• Add new web article on ZIP/ZAP models (zero inflated Poisson models)
  where the non-zero probability is modelled with a separate predictor from the
  predictor for the Poisson model parameter:
  https://inlabru-org.github.io/inlabru/articles/zip_zap_models.html.

Bug fixes and dependency simplification

• Remove dependence on the ggpolypath package, and the
  ggplot2::fortify.SpatialPolygons/DataFrame() methods that were deprecated in
  ggplot2 version 3.4.4. Code using gg.SpatialPolygons() together with
  coord_fixed()/coord_equal() for coordinate axis control needs to use
  coord_sf() instead.
• Detect the need for vectorised parameters in bru_forward_transformation to
  allow bru_mapper_marginal to be applied with e.g. spatially varying parameters.
  (version 2.10.0.9001)
• Detect terra version >= 1.7-66 that removes the need for
  detecting special cases (nrow(where) == 1 and terra::nlyr(data) == 1).
  Workaround code used for versions < 1.7-66. (version 2.10.0.9002)
