v6.1.0 - Bugfixing, matrix and expression performance, better stubs

[Joao-Dionisio]

This was a very active month. Thank you to @Zeroto521 for all your work on improving PySCIPOpt's performance, and thank you, @jonathanberthias, for the introduction and continued support of type stubs. Thank you to all the others who helped during this time, either with PRs or by reporting bugs.
Several of the repo's oldest issues have been addressed (for the curious, #1150, #993, #1161, #1151, #1132).
PySCIPOpt is entering a new phase, with more people contributing and becoming active participants in the repo. Makes me very happy; it's a sign of a vibrant community. This does increase the maintenance effort, so if you would like to help in that regard, please contact me by email (joao.goncalves.dionisio@gmail.com).
