feat: Add Poppler

[principis]

I manually annotated the Action class.

if you annoted something manually you need to mark it like this

# override
class Action(GObject.GBoxed):
...

this tells the generator to not override the class definition if we rerun it.

I've added the # override for the Action class and also for the Page.get_size method. The Size class I created in the second commit does still removed. Is it possible to solve that?

I also added the ellipsis' back in the Action class. I'm not sure if they are needed or not... But there is always a default value set.

why was the Size class needed? Is it a namedtuple that is returned?

did you try to add override to the size class?

[principis]

Yes, it returns a NamedTuple as far as I know. I used this PR as an example, because I didn't really know how to solve it.

This is what is returned by Page.get_size() :

>>> print(type(page.get_size()))
<class 'conflib.pdf.page._ResultTuple'>

>>> print(page.get_size())
(width=612.0, height=792.0)

>>> print(dir(page.get_size()))
['__add__', '__class__', '__class_getitem__', '__contains__', '__delattr__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__getnewargs__', '__getstate__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__iter__', '__le__', '__len__', '__lt__', '__module__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__repr_format', '__rmul__', '__setattr__', '__sizeof__', '__slots__', '__str__', '__subclasshook__', '__tuple_indices', '_new_type', 'count', 'height', 'index', 'width']

Edit: I also tried to add # override, which didn't work...

[lovetox]

Ok, i think we just have to think about it for now if we ever regenerate the stubs

[principis]

Thanks!
