tidyterra 0.3.0

• Package back to CRAN.

• Libraries dplyr, tidyr, tibble are not attached by default.
  Needed functions are reexported instead.

• Improvements on geom_spatraster():

  • Now in geom_spatraster() is possible to avoid the default fill of
    the layer using geom_spatraster(fill = NA) or
    geom_spatraster(aes(fill = NULL)).

  • aes(fill = ggplot2::after_stat()) now works on geom_spatraster().

  • Internal: Better handling of aes() and layers

• Add new function stat_spatraster().

• Reduce the size of external files.
