Inherit ChunkField from int, Enum

[CptGibbon]

Fixes #2209

The lint failure has nothing to do with this PR 😅

I used the int mixin form instead of IntEnum because I couldn't find which version of Python introduced IntEnum.
If there's a good reason to use IntEnum I can of course change it.

[gsingh93]

I just changed the version at the top of the python docs to check if it still existed in an older version, and it does: https://docs.python.org/3.6/library/enum.html#enum.IntEnum

But I'm fine with the mixin too.

BTW, GitHub actions should have an Ubuntu 24.04 runner image now we can use that would have caught this issue. And/or we should add it to docker.

Did you test with Python 3.11/3.12, or should we update the CI first and see if this PR passes?

@gsingh93 I am using python3.11 and it is working for me.

@xtexChooser just to be sure: you mean this PR is working for you? or code before this PR?

[xtexChooser]

@disconnect3d this PR does fixed the error mentioned above for me, although I am still experiencing #2171 and #1754.

[disconnect3d]

Fwiw https://github.com/python/cpython/blob/main/Lib/enum.py#L1328-L1337

@xtexChooser Which error are u getting with #2171?

Is that about ptrace scope? If so, that's purely privileges issue on your side. If that is something else, that's a Pwndbg bug.

Regarding #1754 I don't have time currently to look at it, I'd appreciate any help in debugging/investigating or fixing it. It seems like a GDB/GDBServer bug, but maybe it isn't, I am not sure. If its GDB-GDBServer bug, we should report it to upstream GDB project bugzilla.

@disconnect3d For #2171, the AttributeError, which is mentioned to be a upstream bug. For #1754, it happens when connecting to a x86_64 QEMU VM (the QEMU option -s) after gdb-ing a i386 ELF, only when the architecture of the qemu server differs from the ELF's. (seems to be a GDB bug, it is still here even when pwndbg is not loaded
Thanks for merging this PR.
