- group all `base, placement = self.rebase(baseface)` in one place
- group all normal calculations in one place
- fix placement of tool (bug introduced by my previous PR)
- allow multiple faces when face is created by FaceMaker
- remove unused code: if `len(obj.Base.Shape.Edges) == 1` is true, then there is a Wire and `obj.Base.Shape.Wires` should be also truthy
‣ Make countersink and counterbore on metric holes freely definable by user.
‣ Fixed the Naming of M1.6, M2, M2.5 and M3.5
‣ Added constructor for custom enums from Enums to PropertyEnumeration
‣ Put definitions of cut-types (counterbore/countersink) for
screwtypes into json-files for easy modification.
‣ Allow users to put its own definitions in json-files in
[UserDir]/Mod/PartDesign/Resources/Hole
‣ Contains several examples of cut-type definition json-files that are
propably not production-ready.
This uses a local copy of nlohmann::json¹ to read json-files.

fix a problem with counterbore and countersink in PartDesign Hole feature.
It was not possible to custom define counterbores or countersinks if a
metric thread hole was selected.
Handle the cut-types None, Counterbore and Countersink euqal
regardless of type of thread and let the user customize:
None: none
Counterbore: diameter and depth
Countersink: diameter and angle
The reason for this behaviour is that root point (origin) and axes are not treated as fixed geometry. Every external geometry has negative ID which is at most GeoEnum::RefExt defined as -3 in the file src/Mod/Sketcher/App/SketchObject.cpp. Ids of root point and axes are also defined in this file with id -1 for root point and horizontal axis, and -2 for vertical axis. To fix the problem, GeoEnum::RefExt id was replaced by root point id in the condition checking for the largest id of fixed geometry.
