Memory leaks

[BishopWolf]

I ran a Snyk code analysis, and it detected these problems:

1. Leaking memory. GateRandomMultiGauss is allocated on the heap and never freed
   

   opengate/core/opengate_core/opengate_lib/GateSingleParticleSourcePencilBeam.h

   Line 51 in fcaae6d

   GateRandomMultiGauss *mGaussian2DXTheta =

2. Leaking memory. G4AffineTransform is allocated on the heap and never freed
   

   opengate/core/opengate_core/opengate_lib/GateUniqueVolumeID.cpp

   Line 120 in fcaae6d

   auto t = new G4AffineTransform(rotation, translation);

It also detected

Calling extractall to extract all files from a tar file without sanitization. This may result files outside destination directory to be overwritten, resulting in an arbitrary file write.

opengate/core/opengate_core/g4DataSetup.py

Line 104 in fcaae6d

tar.extractall(path=dataLocation)

Thanks for reporting. That's helpful.
We will put this on the list of issues to be addressed in the next weeks.

By the way: Do you mind sharing the commands you used to do the code analysis? I am honestly not familiar with Snyk. Thanks a bunch.
