- fixed bug in ToolCutout where creating a cutout object geometry from another external isolation geometry failed

- fixed bug in cncjob TclCommand where the gcode could not be correctly generated due of missing bounds params in obj.options dict
- fixed a hardcoded tolerance in FlatCAMGeometry.generatecncjob() and in FlatCAMGeometry.mtool_gen_cncjob() to use the parameter from Preferences
