Fornjot v0.49.0 - open source b-rep CAD kernel in Rust

After three months since v0.48.0, it's time again for a new release of Fornjot!

This has been a bit of a transitionary release, with lots of work started but not finished yet. There are still some goodies in there though.

Please let me know, if you have any questions. Happy to answer what I can!
