* changed common.c readADCFromFile to make it more general and move temperature calculation for Eiger out of this function and inside whereever it is called.
* g2 and m2: gethighvoltage was just a variable set in server, it is now moved to a get inside DAC5671 implementation (but not reading a measured value, instead what is set from a file), high voltage variable used inside DAC5671 for virtual servers
* g2: switching off hv (ifrom non zero to zero value) will wait for 10s; powering on chip reconfigures chip; powering off chip unconfigures chip; powering off chip also includes check if hv = 0, if not throw exception; chip configuration checked before acquring; at start up: hv switched off and chip powered on, so does not wait 10s to switch off hv;
* included test to check powering off chip when hv is on should throw an exception
* g2: check if chip configured before acquiring
* nios: read hv value set from file and virtual still goes into DAC5671 for conversions to and fro dac to V, change common readadc to readparameter to generalize, make sethighvoltage into a get and set to catch errors in get as well, g2: if not at startup, remmeber hv value before setting it and after check if value was being switched off (from a non zero value) and wait 10s if it was (10s wait only for switching off from non zero and not at startup)
* eiger: hardwareversion, fix firmware version unable to read version scenarios, check to see if febl, febr and beb have same fw version
* feb versions can be picked up only after feb initialization
* eiger: adding mask to read/write registers. useful for setting quad parameters as they might have different values for left and right fpga registers.
** fix quad position
* fix quad flipping
* formatting
- eiger server: fix for fw workaround where stop acquisition processing done signal does not come up, by removing reset in stop acquisition and waiting for2 seconds for feb done processing signal to go down, if it doesnt, throw if status is not idle.
- error messages not setup for some eiger server errors
- quad fix (chip signals to trim quad, both left and right registers can be different)
- minor logical error of no consequence (stop acquisition returns a different enum than expected)
