Parameter description parsing captures less indented text of another section #29

Expected behavior: Parameter description ends when there parser encounters less indented line.

Actual behavior: The parameter description capturing does not seem to stop when less indented line is encountered and captures it as well.

def foo():
    '''Converts Keras HDF5 model to Tensorflow SavedModel format.

    Args:
        model_path: Keras model in HDF5 format.
        converted_model_path: Keras model in Tensorflow SavedModel format.

    Annotations:
        author: Alexey Volkov <alexey.volkov@ark-kun.com>
    '''

The description for converted_model_path becomes:

Keras model in Tensorflow SavedModel format.
Annotations:

P.S. It would be really great if it was possible to parse additional sections that are not currently recognized by the docstring_parser.
