Number of scale in WaveletN can exceed the allowed maximal value

[LElgueddari]

The number of scale can be set to any value including one that might have some boundary effects.
The allowed number of scale must be bounded by its maximal value

Hmm, this seems to be an issue that needs to be targeted at pysap, ideally pysap must hold a method to give maximum value for number of scale.
