This fixes a bug on Windows that caused the contour of some meshes to be
extracted incorrectly.

Memory consumption is now very low and performance is much better with huge files.

This is achieved by using low-level TelemacFile functions to avoid the need to
rely on a memory buffer when using Hermes.

Replace the removed function inspect.getargspec with inspect.getfullargspec

This was no longer necessary since telemac_cas.get_dico is able to find dictionaries correctly.
Also remove the redudant api_module.get_dico function.

These belonged to the previous XML-based validation system

It no longer raises an invalid exception, and exit gracefully when "--bypass" is used.

This also fixes contour extraction with global models and ensure that outer and inner contours are oriented properly.

The leak was caused by a circular dependency between Matplotlib.LinearTriInterpolator
and its internal trifinder instance, so that both instances were never released.
