Dev/rx callbacks (#966)

* changed rxr callback signatures to all include structs
* removed datamodify call back as size can be changed in the original data call back now
* bringing some parameters (set functions) to dataProcessor class for its callback (namely udpport, quad, fliprows, totalframes, jsonheader), resulting in also removing totalframes from 2 other function signatures

* updated MultiReceiverApp to reflect the new callback signatures
