Math Nodes not working onPython 3.14

[n0valis]

Unfortunately with Python 3.14 we are running into trouble with the MathExpression|pysssss Node

File "/opt/ComfyUI/custom_nodes/comfyui-custom-scripts/py/math_expression.py", line 182, in eval_expr
if isinstance(node, ast.Constant) or isinstance(node, ast.Num):
^^^^^^^
AttributeError: module 'ast' has no attribute 'Num'

As ast.Num is deprecated maybe just change it to if isinstance(node, ast.Constant)
