Threshold and charge DAC conversion for Star
A class to handle the conversion of BVT to mV and BCAL to fC for the Star chips.
I took and modified the StarConversionTools class from the devel_SR1 branch. It can load a calibration config file if provided, otherwise it calculates the conversion from a linear function.
The StarConversionTools is added to StarCfg as well, so it can be retrieved from feCfg in an analysis.
