Highlights
* reworked integration engine to use solve_ivp from SciPy which supports events (new EVENT block)
* more notebooks and examples
* reworked dynamic block loading, much faster
* type hinting throughout, increased test coverage
* bdedit reliability improved, now uses PySide6, periodic and crash model saving, formalized interface to bdsim and improved robustness of block parameter parsing
* sampled-data block support now equivalent to continuous time
* working DERIV and PID blocks
* LTI_SISO and LTI_SISO_S support various canonical state-space forms
* improved error messages and exception handler text
* scope blocks have data cursor, dark/light theme, can be tiled into a container window
* state handling is now more rational, no state in blocks anymore
* simplified/faster transport of results between blocks using new PortValueSlot objects
* changes to scheduler to allow direct feedthrough dynamic blocks
