- fixed a number of issues, mostly leftovers from moving the UI of a Plugin in its own class
- fixed some bugs in the Punch Gerber plugin
- fixed some bugs where the 'pool' parameter was not passed when creating shapes collections (in 3D graphic mode); I wonder how it worked until now
- added a new feature in the Isolation Plugin: now for all the isolation Geometry objects this plugin can do a supplementary simplification of the geometry using the tolerance parameter defined in the General Parameters. This should lead to a reduced number of tool lifts when doing corners
- fixed some outstanding issues from the PyQt6 port
- PEP8 fixes
- minor fixes
- updated the saving of Preferences to update the self.options too: the `Apply` action will update the self.options but the `Save` action will save the updated preferences to the file on disk
- added ability to copy the coordinates of the exclusion area with the context menu actions in the Exclusion areas table found in the Milling/Drilling plugins
- added a bilinear interpolation calculation class from: https://github.com/pmav99/interpolation
- in CNCJob UI Autolevelling: made sure that the grid can't have less than 2 rows and 2 columns when using the bilinear interpolation or 1 row and 1 column when using the Voronoi polygons
- in CNCJob UI Autolevelling - Voronoi polygons are now plotted
- in CNCJob UI Autolevelling - adding manual probe points now show some geometry (circles) for the added points until the adding is finished
