autopep8 removes whitespace before array slice, creating code not compliant with PEP 8

[hannob]

In the code example below, autopep8 removes a whitespace before the ":" array slice operator, turning

    v = input[n * 16 : n * 16 + 15]

into

    v = input[n * 16: n * 16 + 15]

I believe this is a bug. According to the PEP 8 documentation here
https://peps.python.org/pep-0008/#whitespace-in-expressions-and-statements
it says:
"However, in a slice the colon acts like a binary operator, and should have equal amounts on either side (treating it as the operator with the lowest priority)."
