Akaze: add a describer type through commandline

[sarveshkoyande]

I am currently able to use paramOverrides with maxpoints, feature extraction presets, guidedmatching and meshing angle.

However I would also like to change .DescriberTypes to include akazi.

For the input FeatureExtraction.describerTypes=akaze

The program terminates with.

ValueError: ChoiceParam value "a" is not in "['sift', 'sift_float', 'sift_upright', 'akaze', 'akaze_liop', 'akaze_mldb', .......

When I use .describerTypes=sift

It says choice param value "s" is not in list.
Similarly, it takes whatever text i mention and only reads the first letter of the input.

Could not find any discussion on this topic, please help
