Fix for python 3.11

[f3rn0s]

This fixes the issue with _decompose calls...

Essentially, if python supports converting the IntFlags into a list, we do it, otherwise we fall back to old behavior.

See #108 for details.

Tested this change out on https://github.com/Orange-Cyberdefense/GOAD, seems to work fine :).

Also definitely backwards compatible:

hmmm, looks like the string conversion isn't quite right... I'll take a look

Turns out .to_str_list() was calling the old .to_list method which wouldn't return the correct data, so just had to update that function too.

Results in the json are now correct:

      "Enrollment Flag": [
        "IncludeSymmetricAlgorithms",
        "PendAllRequests",
        "PublishToDs",
        "AutoEnrollment"
      ],

Where previously it would return the integer representations of these flags.

Looks like the Certipy will have these always exist:

"Private Key Flag": [
    16777216,
    65536
],

Similar to:

Enrollment Flag: [
    None
],
Private Key Flag: [
    AttestNone
],

However using list() makes it so the result doesn't include these (i.e. if it's None, then it will leave Enrollment Flag undefined).

What should the proper handling of this be?
