Update geometry converters to be compatible with DD4HEP
Depends on LHCb!3530 (merged), LHCb!3541 (merged), Rec!2860 (merged), LHCb!3586 (merged), Lbcom!610 (merged), Rec!2913 (merged)
With this MR all services have been converted to algorithms.
Add counters for amount of bytes written to allow standardisation of the dump_for_standalone_allen test, implemented in Moore!1592 (merged).
