unnecessary process in gen.py

it seems L285 in nnsvs.gen.py can be removed and can be changed from

 windows = get_windows(num_windows) 

 # Apply MLPG if necessary 
 if np.any(has_dynamic_features): 
     static_stream_sizes = get_static_stream_sizes( 
         stream_sizes, has_dynamic_features, len(windows)) 
 else: 
     static_stream_sizes = stream_sizes

to

 # Apply MLPG if necessary 
 if np.any(has_dynamic_features): 
     static_stream_sizes = get_static_stream_sizes( 
         stream_sizes, has_dynamic_features, num_windows) 
 else: 
     static_stream_sizes = stream_sizes
