Measurment: Minimal wall thickness analysis

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Problem description

Currently there's no way to automatically compute the minimal wall thickness. Models intended to be 3D printed or moulded require some minimal wall thickness according to the manfuacturers specs. When the model gets complex it's close to impossible to manually measure or compute the minimal thickness.

I therefore propose a way to automatically compute the minimal wall thickness (Design for Manufacturability). The draft analysis of the curves workbench does a similar pre-manufacture analysis, but it's intended for injection mould models. The minimal wall thickness analysis would be beneficial for 3D prints as well as moulds.

Here's additional info including a algorithm: [On edge cases in CAD thickness analysis](https://quaoar.su/blog/page/edge-case-in-cad-thickness-analysis)
The source code of an implemenation of said algorithm: [Github - AnalysisSitus](https://github.com/CadQuery/AnalysisSitus)
