[Feature] Introduced option to control amount of internal bridging, fixing internal bridge missing for some sloped surfaces (#3319)

Browse source 
* ENH: Improve internal bridge detection for sloped surfaces

* Moved lightning detection out of the parallel threads

* Naming conventions

* Revised approach - use reduced expansion multipliers

* Further reduce filtering, flagged option as experimental

* Corrected code comment

* Updated tool tip

* Introduced filtering drop down option
