* moved options and parameters code into a new file
* many small-ish fixes and improvements
* fix compatibility to numpy 2.0 (thanks to Sait Cakmak)
* improved interface to noise_handler argument which accepts True as value
* improved interface to ScaleCoordinates now also with lower and upper

* assign surrogate attribute (for the record) when calling fmin_lq_surr
* various (minor) bug fixes
* various (small) improvements of the plots and their usability

* subtract any recorded x from the plotted x-values by x_opt=index
* plots are now versus iteration number instead of evaluations by default
* provide legacy bbobbenchmarks without downloading
* new: CMADataLogger.zip allows sharing plotting data more easily by a
zip file
* new: tolxstagnation termination condition for when the incumbent
