_quantize_mx() is not handling axes=None proper

[teabun]

It seems _quantize_mx() is not properly handling axes=None.

At

microxcaling/mx/mx_ops.py

Line 194 in 7bc4195

axes = [x + A.ndim if x < 0 else x for x in axes]

    return _quantize_mx(
  File "c:\mx\microxcaling\mx_ops.py", line 194, in _quantize_mx
    axes = [x + A.ndim if x < 0 else x for x in axes]
TypeError: 'NoneType' object is not iterable 

Should not axes be initialized to shape of A if None?
