Type stubs for cftime

[BSchilperoort]

Type stubs can add type information to a python package. Typing can make it easier to write code as IDEs will be able to give (better) suggestions and type checkers can infer if the right types are passed to/from functions.

cftime is currently missing type stubs. I started on writing a stub file for my own use, but this is not complete (and might be incorrect).
