Allow support for Python 3.12

[Tenzer]

Python 3.12 was released on 2023-10-02, and this extension should work in the new version without any code changes. The configuration for the project, however, doesn't allow it to be installed on Python 3.12, but this fixes that.

Note: This doesn't remove support for Python 3.7 even though that has reached end-of-life. Let me know if you'd like me to remove support for that here as well.

The CI run at least shows frozenlist needs to be updated - which requires dropping Python 3.7 support, otherwise, Poetry won't select the latest version of the package because they have dropped 3.7 support. I, by the way, noticed b1e949a, so I guess dropping support for Python 3.7 is okay since it's not being tested anyway.

yarl also needs to be updated. aio-libs/yarl#881 has been merged to add support for Python 3.12 but there's no release with those changes yet, so I guess this probably will have to wait until they have made a new release.

@Tenzer, we can drop 3.7 support. It was already removed from the Thumbor main project.
Thanks for the contribution.

@Tenzer , I'm removing Python 3.7 on #153

I got a bit further with this now but hit a couple of other roadblocks:

1. Scipy needs to be updated to at least version 1.11.2 for wheels to be available for Python 3.12 (release). It has, however, already dropped support for Python 3.8, meaning we also need to drop Python 3.8 support, otherwise, Poetry won't allow Scipy 1.11.2 to be installed.
2. aiohttp is a dependency of aiobotocore. They do have Python 3.12 support but it's only available as a prerelease in version 3.9.0b0. They are working on getting that released properly, tracked in ** 3.9 Beta testing ** aio-libs/aiohttp#7675.

I have rebased the changes and dropped Python 3.8 support in order to get the updated Scipy that works with Python 3.12. Tests are successful for me now.

@Tenzer , this might be an issue, since Thumbor still supports Python3.8.

[guilhermef]

@Tenzer, you can pin Python 3.8 to scipy 1.10.1 and the others with a newer version.

Good idea. I have kept the version range the same for Python 3.8 support for now, but we can bump that if you want. Python 3.9+ are using the version of NumPy and SciPy that has 3.12 support.

Thanks for the contribution @Tenzer

You're welcome!
