Title: Extends the CF Checker, adds more Chapter 4 checks

- Moves DSPair to module scope
DSPair is used by the compliance checkers and its structure is
implicitly required in the Checker classes 'setup(self, ds)' methods.
This commit moves DSPair to the module scope and explicitly defines two
class attrs representing the struct elements.

- Adds tests for Chapter 2
- Adds static files for compliance checking
- Adds CF checks for Chapter 4
- Coordinate vars for coordinate types
- Latitude checks
- Adds 4.1 and 4.2 checks and tests
