M3threshold (#475 )

* vicin default changed to 800, only setting vthx directly allows to set dac even if counter disabled, else disable counter, setallthresholdenergy if an energy is -1, get module value, fix that reg was repaced by isettings * vth3 disabled for interpolation enable, interpolation disable sets counter mask to what it was before (updating old mask whn setting counter mask except for setting all counters for interpolation enable) and enabling vth3 if counter was enabled * refactor and test for previous commit * pump probe only has vth2 enabled, handles both pump probe mode and interpolation mode as well * wip * refactored pump probe and interpolation and added to setmodule * check dacs and trimbits out of range for setmodule (not just threshold) * binaries in * m3: pump probe and interpolation mutually exclusive * minor
m3 and g2: change in system clock (clkdiv2) should also change the time settings(exptime, period, gate delay etc.), g2: sys freq same irrespective of external or internal timing source (#470 )

 - gotthard 25 um image reconstructed in gui and virtual hdf5 (firmware updated for slave to reverse channels)
 - master binary file in json format now
 - fixed bug introduced in 6.0.0: hdf5 files created 1 file per frame after the initial file which had maxframesperfile
+- rx_roi
 - m3 polarity, interpolation (enables all counters when enabled), pump probe, analog pulsing, digital pulsing
 - updatedetectorserver - removes old server current binary pointing to for blackfin
 - removing copydetectorserver using tftp 
->>>>>>> developer
 - registerCallBackRawDataReady and registerCallBackRawDataModifyReady now gives a sls_receiver_header* instead of a char*, and uint32_t to size_t
 - registerCallBackStartAcquisition gave incorrect imagesize (+120 bytes). corrected.
 - registerCallBackStartAcquisition parameter is a const string reference
 - m3 (runnig config second time with tengiga 0, dr !=32, counters !=0x7) calculated incorrect image size expected
 - fixed row column indexing (mainly for multi module Jungfrau 2 interfaces )
 - eiger gui row indices not flipped anymore (fix in config)
+- m3 (settings dac check disabled temporarily?)
+- m3 virtual server sends the right pacets now
+- gap pixels in gui enabled by default
+- rxr src files and classes (detectordata, ZmqSocket, helpDacs) added to sls namespace, and macros (namely from logger (logINFO etc)), slsDetectorGui (make_unique in implemtnation requires sls nemspace (points to std otherwise) but not deectorImpl.cpp)
+- blackfin programing made seamless (nCE fixed which helps)
+-save settings file for m3 and eiger
+- m3 threshold changes
+- g2 and m3 clkdiv 2 (system clock) change should affect time settings (g2: exptime, period, delayaftertrigger, burstperiod, m3: exptime, gatedelay, gateperiod, period, delayaftertrigger)
+- g2 system frequency is the same irrespective of timing source
+- (apparently) rxr doesnt get stuck anymore from 6.1.1
