WHL: enable cp314 wheels

[neutrinoceros]

Rationale

I missed the opportunity to do this in time for 0.25.0, but I just tried this on my fork and saw no compilation error, so I'm proposing this change now.
I notice the wheels are not immediately tested, so I'm adding 3.14 to CI too (but I haven't tried that part on my fork yet, so, opening as a draft)

Implications

Removing CIBW_BUILD has the effect of letting cibuildwheel take the wheel (pun intended) and select target versions for you, where

• the oldest Python version is either the oldest supported by cibuildwheel itself (currently 3.8) or the oldest version compatible with project.requires-python, as specified in pyproject.toml, whichever is newer.
• the newest Python version selected depends on your pinned version of cibuildwheel, and usually include all ABI stable versions, so currently this goes up to 3.14

I'm however also adding a filter to CIBW_SKIP, otherwise cp314t wheels are also included by default, and I don't know what your plans are in this area.

Ah, of course pyproj doesn't trivially build from source so it's still a bit early to add 3.14 to CI.

[greglucas]

Yeah, I figured that would be the case, so I didn't try too hard on the 3.14 aspect since we are still in rc's on many projects. Lets not wait another year to make a release though (note to self ;) ) so once our dependent projects release their wheels we should try to build and publish ours as well.

I might forget about this PR when the time comes, so please don't hesitate to do what you please with it if it's any help in the future !

FYI (as I'm reviewing what packages I depend on have 3.14 and free-threading enabled) my PR to pyproj just got merged to main. The release to PyPI isn't expected until September from what I was told and will include a bump in the PROJ version as well.

[neutrinoceros]

Thanks ! I'll try to come back to this in a month or so and see where things are then !

[neutrinoceros]

Looks like pyproj 3.7.2 came early with cp314 wheels, so let's try this one more time

[neutrinoceros]

the current blocker is now shapely

[djhoese]

Dang you're quick. I just released pyproj a couple hours ago.

[neutrinoceros]

(I get RSS alerts for many PyPI package, including pyproj :))

[neutrinoceros]

shapely 2.1.2 is out with cp314 wheels, let's try this again

[neutrinoceros]

current blocker: fiona
this one is only an optional dependency though, so it should be possible to avoid it.

[neutrinoceros]

Oh wait that's only for the regular CI part, let me just drop that real quick then

[neutrinoceros]

wait, the wheel job didn't run. Can someone add the "Run cibuildwheel" label please ?

[QuLogic]

I'm not against freethreaded wheels, but I'm not sure if they work.

[QuLogic]

Hmm, actually, this does nothing, because the freethreaded one is missing the trailing *.

[neutrinoceros]

thank you. Fixed
