Add proj_degree_input() and proj_degree_output()
Equivalent to proj_angular_input() and proj_angular_output() but
checking for degree units instead. proj_create_crs_to_crs() rarely, if
ever, returns pipelines that has radians as input or output so using
proj_angular_*() is not a useful check for io units of pipelines.
These two new functions should make life a bit easier for users that
generally store there angular coordinates in radians.
Closes #2027
