change type of macro pulse number PV to int64_t (as this is the data type expected by DOOCS) and convert if necessary via the TypeChangingDecorator

- Replace the std::reference_wrapper<TransferElement> with a TransferElementAbstractor.

Fixed a type confusion between int64_t (aka long int on 64 bit platforms) and long long int. The types are not identical (in the C++ sense) but bit-compatible. ChimeraTK expects int64_t while DOOCS expects long long int.

removed direct use of CSA::ProcessArray (which is the implementation) and replaced it with NDRegisterAccessor (the base class) in the adapter. Usage in tests still pending

moved to the "ProcessVariableAccessors" branch of the control system adapter, which unifies the interface with DeviceAccess

  -- kind of seems to work with jddd_tool (strange update behaviour)
  -- automatic tests missing
- Fixed the use of process variables with location name
