Description
This fixes use of the EGAIN FITS keyword and introduces the GAIN FITS keyword.
A new ICamera interface named ElectronsPerADU has been introduced to allow a camera driver to report e- per ADU for the sensor. If present, this value is assigned to the EGAIN FITS keyword. The actual camera gain is now reflected in the GAIN keyword. ElectronsPerADU is a double and camera drivers should report NaN if they are not able to provide this value.
