[CSM] Add function to set minimap shape (#5569)

* [CSM] Add function to set minimap shape

Also deprecates `toggle_shape`.

* Oh fish, I messed that one up!

* Fix Style

* Sorry, I missed something

I still had the `luamethod` call in there!

* Add getters

* Remove extra line

* Remove useless variable

Please review again @nerzhul . Thanks!

* Satisfy nerzhul
