C handle init

[trevorhardy]

Add __init__() definitions for all classes that inherit from "_HelicsCHandle()". This fix was necessary for allowing the implementation of a query callback (specifically providing the init to "HelicsQueryBuffer").

Do we know how to fix the failures here

[trevorhardy]

For all the functions that inherited from "_HelicsCHandle" I implemented the fix that Mark put together (initializing with the super classes init) and I'm 99% sure that this will provide at least a good-enough band-aid to make things not fail like they were for us. Once we have a new PyHELICS expert they should go through capi.py and figure out how to do this better.

Getting a lot of

tests/test_api.py:13: in <module>
    import helics as h
helics/__init__.py:2: in <module>
    from .capi import *
E     File "/Users/runner/work/pyhelics/pyhelics/helics/capi.py", line 1477
E       class HelicsQueryBuffer(_HelicsCHandle):
E       ^
E   SyntaxError: invalid syntax

in the testing

[trevorhardy]

Let me see if there's something I've obviously done wrong.

[trevorhardy]

Stupid missing ")", double-checking I didn't copy-paste this everywhere and then I'll push back up. Should be just a minute.

[trevorhardy]

Ok, let's try this again.

[trevorhardy]

I'm feeling good about this one....

Maybe the filter test should be marked as skip on Windows? Access violation sounds like it is crashing in the C/C++ part of the HELICS library.

[trevorhardy]

I don't know enough to say whether skipping that test is a good idea but I like seeing one more green checkmark.

[nightlark]

It is strange how it passes for the CI job triggered by the "push"/commit, but fails for the "pull_request" trigger; also the test passed in the CI job for the merged PR earlier passed in the main branch.

[trevorhardy]

Use Python 3 style super().

If we've dropped Python2 support, I'm on board. If we haven't, we should keep it the same way.

[nightlark]

We dropped Python 2 support. Our CI jobs couldn't even install Python 2.7 to run tests without failing.
