v6.3.0 - Expression performance, more stubs, and more interfaced methods.

[Joao-Dionisio]

In this release, you can find performance improvements in expression handling, more stubs, and some more interfaced methods.

The next non-bugfix release will probably come with support for SCIP's next major release, SCIP 11, planned to come in early 2027. This will also contain some bugfixes that had been found in PySCIPOpt, so the software will be more robust. I'm also hoping to add some extra functionality to PySCIPOpt on top, so be sure to stay tuned.

Thank you to @Zeroto521 , @jonathanberthias , @MySweetEden , @adamj34 , @tias , @mohitt31 , @musicinmybrain , @mkoeppe , @abb-omidi , and everyone else for contributing, being a part of the community, or simply using the software. We are neeeearly at 1000 stars, and should cross it before the end of the year. Fingers crossed 🤞

Below you can find the changelog.
