Including IDEA vertex detector (that is not just a scaled copy of the CLD one)

[armin-ilg]

Hi there

This is my current implementation of the IDEA vertex detector, following the design of Fabrizio Palla and Filippo Bosi from INFN Pisa (see e.g their last presentation in the detector concept meeting in November).

This is closely linked to the PR from Andrea for the smaller beam pipe, that this vertex detector relies on. I started in May using the version of the beampipe from back then.

The status at the moment is:

• Vertex inner barrel: Quite realisic implementation using support + sensitive sensor + sensor periphery + flex
• Vertex outer barrel: Layers are at the correct R but many other things are missing, WIP
• Vertex end-cap: Just using CLD-like endcaps for the time being, more realistic implementation WIP
• Outer Si Wrapper (with timing): Not started yet, but will likely use same moduel as vertex barrels

For this code to run, also the correct lcgeo and DD4hep versions need to be used, here are the links to the PRs/Forks there:

• DD4HEP: my fork
• lcgeo: my fork

Other things I did here:

• Using beam from Detector/DetFCCeeCommon
