Description

Following https://github.com/extendr/extendr/pull/853 we should document using external pointers with extendr.

- what is an external pointer in general
- using them to point to native rust structs
- cannot be interacted with from R directly—unless using extendr-impl
- creating functions that expect external pointers
- cloning external pointers (what does this do?)
