{absmaps} is depreciated; use alternatives

This package is hard depreciated and will be removed from Github shortly. It is replaced by:

1. {absmapsdata}: contains compressed, tidied, and lazily-loadable sf objects that hold geometric information about ABS data structures.. Install with: remotes::install_github("wfmackey/absmapsdata").
2. {strayr}: contains a helper function, read_absmaps(), to download sf objects from {absmapsdata} on demand.. Install with: remotes::install_github("runapp-aus/strayr").
