SourceXtractor FATAL : boost::bad_get: failed value get using boost::get

[mkuemmel]

A user (OU NIR) permanently got the following error when running on their data:
SourceXtractor FATAL : boost::bad_get: failed value get using boost::get

Turns out the problem is the int keyword:
SATURATE= 64511

but here the kewyword is expected to be double:

SourceXtractorPlusPlus/SEImplementation/src/lib/Configuration/DetectionImageConfig.cpp

Line 85 in c3d57ab

detection_image_saturate = boost::get<double>(img_metadata.at("SATURATE").m_value);

The same is true for "GAIN" and "FLXSCALE" around this code line.
