[BUG] Diagnostics for BasicMotions with HC2, numba stripped out

[TonyBagnall]

stripped out njit to the point where it still passes locally, seems to have narrowed it down to shaplet transform

after this the next stage is ShapeletTransform

_extract_random_shapelet (not njit)
@njit methods
z_normalise_series
_find_shapelet_quality
_online_shapelet_distance (this has a bespoke std calculation that calls math.sqrt. It also calls zip)
_calc_early_binary_ig
_binary_entropy
_calc_binary_ig
_binary_entropy

whats weird to me is if I turn numba off on the outermost method, _find_shapelet_quality, it crashes,

 File "C:\Code\aeon\aeon\transformations\collection\base.py", line 327, in _fit_transform
    self._fit(X, y)
  File "C:\Code\aeon\aeon\transformations\collection\shapelet_based\_shapelet_transform.py", line 297, in _fit
    candidate_shapelets = Parallel(
  File "C:\Code\aeon\venv\lib\site-packages\joblib\parallel.py", line 1918, in __call__
    return output if self.return_generator else list(output)
  File "C:\Code\aeon\venv\lib\site-packages\joblib\parallel.py", line 1847, in _get_sequential_output
    res = func(*args, **kwargs)
  File "C:\Code\aeon\aeon\transformations\collection\shapelet_based\_shapelet_transform.py", line 446, in _extract_random_shapelet
    quality = self._find_shapelet_quality(
  File "C:\Code\aeon\aeon\transformations\collection\shapelet_based\_shapelet_transform.py", line 513, in _find_shapelet_quality
    quality = _calc_binary_ig(orderline, this_cls_count, other_cls_count)
TypeError: can't unbox heterogeneous list: UniTuple(int64 x 2) != Tuple(float64, int64)

logically, I thought you should be able to turn off the outer methods

so seems ST is the culprit.
