Closed Issue: [0.1.x] typedVar for array types does not work with slice and negative indices [10613]

Reproducing test:
 
def testArrayFieldSlice(self):
tv = target.module.typedVar( "g_struct3" )
self.assertEqual( 2, tv.m_arrayField[-1] )
self.assertEqual( [ 0, 2 ], tv.m_arrayField[0:2] )
Comments: close all old bugs
