## What is the bug
This MR:
* Reverts all variables in `set_zlev()` back from double-precision to working-precision.
* Adds a single & double precision variants (previously working-precision) of `rotate_latlon()`

## Details
Reverting `set_zlev()` changes I introduced in !13

. This will only effect single-precision builds.
