LJpegDecompressor implicit conversion issue

../src/librawspeed/decompressors/LJpegDecompressor.cpp:193:27: runtime error: implicit conversion from type 'int' of value 72278 (32-bit, signed) to type 'std::array<unsigned short, 2>::value_type' (aka 'unsigned short') changed the value to 6742 (16-bit, unsigned)

Start at line 193 of src/librawspeed/decompressors/LJpegDecompressor.cpp and reproduce the report with the supplied KDRaw_Q360_20190310_125715_000001.dng file using the sanitizer build and rstest. Done means the sample no longer triggers the UBSan implicit-conversion report or terminates rstest with signal 6.
