Generalize the functionality of converting parameters

[jmcarcell]

so that a Frame may be passed or not. This is needed to use IOSvc with the Marlin wrapper, because in that case there is not a frame that is passed around like with the PodioDataSvc.

• Make convertObjectParameters take a function object as argument that deals with actually handling the parameter storage on the EDM4hep side. This allows to generalize its usage to cases, where a podio::Frame is not directly accessible, but some other functionality for storing parameters is available.

There are multiple ways of solving this but given that the convertObjectParameters function is only used in the wrapper I think this is the simplest one even if it changes the interface.

edit: removed the tags for the tagging script as this has been reverted again in #105 so it should not end up in the release notes.

I have added a second template parameter to this and introduced the ParamFramePutter helper struct that can be passed to it for putting things into a Frame. A similar struct can be used in the k4MarlinWrapper to switch to k4FWCore::putParameter instead. This makes it possible to remove the dependency on k4FWCore again.

edit: Also I have put the original overload back for convenience since it's effectively a one line wrapper.
