Fix some ctypes argtypes declarations

The ESMC_MeshCreateFromFile change was needed to fix
#326 (comment) with python
3.12 on my Mac.

The ESMC_RouteHandleCreateFromFile change was needed to fix
#326 (comment) with
python 3.12 on my Mac.

The two other changes weren't causing any visible problems, but were
things I noticed that should be fixed.

Resolves #326
