ACTSFW-99_DD4hepAdaptions
In FCCSW the id of the beampipe is 0. For the ACTS implementation this was changed, because the geometry builders need the geometry to be build from smaller to bigger in order to allow correct wrapping. Therefore the beampipe had the largest id, to be build as last volume. After a fix in the DD4hepPlugin (acts-core!363 (merged)) it is now also possible that the beampipe comes in first. Another problem was that with the forward endcaps of the FCC tracker arbitrary binning is needed in r, because the modules are not equidistant anymore. Fixes ACTSFW-99.
