WIP: DigitizerReceiver
The MR is currently labelled as WIP because it seems we should test this branch on hardware before merging.
[1] This is including the digitizer module and the underlying vx1730 code that is used in the module as a submodule called "digitizerreadout".
[2] There is also an example config file called "config_withDigitizerReceiver.json" with the necessary setup for the DigitizerReceiverModule.
[3] The code is ready to be open-sourced in the sense that all of the proprietary SIS3153 code is housed in a separate submodule that can be made internal.
