Unnecessary Integer cast causes error during ARXML export

[ChristianSteffens]

I might be mistaken, but isn't this integer conversion unnecessary? It causes an error during ARXML export, considering that the signal values are already stored as integers.

canmatrix/src/canmatrix/formats/arxml.py

Line 802 in 8ca6d78

for value in sorted(signal.values, key=lambda x: int(x, 0)):

canmatrix\formats\arxml.py", line 800, in <lambda>
    for value in sorted(signal.values, key=lambda x: int(x, 0)):
                                                     ^^^^^^^^^
TypeError: int() can't convert non-string with explicit base
