* Only one processing thread, move packet processing
  to Camera readRecvPackets and assemblePackets
* Remove Recv helper class in Jungfrau

* Implement Single & Dual modes for raw & processed
  image injection into Lima, respectively
* Support max_memory control similar to CtBuffer

* Add Reconstruction helper for both Eiger & Jungfrau image corrections
* Allow an Acq BufferCtrlObj, in addition to Lima one, for raw images
* Support both 16 & 32 bit GainPed maps
* Disable GainPedImgProc if necessary

* Jungfrau switches to Stopped instead of Idle if stopped

* Port to new Detector & Receiver API
* Enable gap pixels through Receiver patch
* Implement put/getCmd through sls_detector_put/get
* Extend SystemCmdPipe::wait to recover output,
  add execute for commands without input

* Each thread process a whole frame
* FrameMap has only one item

* Call detector stopAcquisition if Model::isXferActive

Lower reliability, probably due to different data streams' speeds

* Each thread process a whole frame
* FrameMap has only one item

* Move Receiver::Thread to Model::Recv::Thread
* Remove FrameMap::Item::Group/Follower/FrameQueue
* Block Receiver::Port threads while Model::Recv::Thread work
* Support arbitrary number of threads, distribute with ThreadBalance
* Remove ExpandInThreads

* Implements & closes #8

* Fix bug in the call order of Model members' constructors

* Remove ReadoutFlags, add ParallelMode
* Disable NetworkParameter support
* Implement missing functionality in API as put/getCmd
