IMOS cheks for attributes being numeric fail incorrectly

[mhidas]

E.g. for this file we get:

    geospatial_lat_max                 :3:     0/ 1 :  
        check_attribute_type           :3:     0/ 1 : Attribute type is not
                                                      numeric
    geospatial_lat_min                 :3:     0/ 1 :  
        check_attribute_type           :3:     0/ 1 : Attribute type is not
                                                      numeric

but this is not true:

                :geospatial_lat_min = -46.94032f ;
                :geospatial_lat_max = -46.94032f ;

Looks like the code expects the type of these attributes to be np.number, which is incorrect (usually they will be np.float32 or np.float64, which are subclasses of np.number)

Problem is that type could either be float32 or float64. Will see if I can combine both tests.

@ggalibert Note that check_attribute_type allows expected_type to be given as a list.

@mhidas I created a PR https://github.com/aodn/compliance-checker/pull/72 to fix this issue.

Fixed via #72
