Sorry about a bug introduced by the pick_points refactor for people that don't have scikit-learn installed. Today I learned something about type hints still being evaluated at runtime. Turns out I just needed to add the from __future__ import annotations at the top of a file.

Please let open a new issue if this just didn't fix it.

Happy Halloween! 👻🦇🎃

What's Changed

• Fix annotations-based bug when user doesn't have scikit-learn installed by @blaylockbk in #492

A few changes have accumulated and thought it was time for a new release.

• You'll notice that index files are now downloaded locally so they can be used when subsetting local files. This has been a requested feature for a long time and I'm grateful for @vieramercado for making a pull request to do that.
• Curl isn't a Herbie requirement anymore, as all the downloads are handeled by the requests library now.
• The pick_points accessor was refactored. I tried to add better tests for this feature (with help from claude), but please let me know if you have issues.

I'm also thining this will be the last version supporting Python 3.10. When eccodes binaries for 3.14 are relased, I'll test Herbie with Python 3.11, 3.12, 3.13, and 3.14.
