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 https://github.com/OpenGATE/opengate/blob/fcaae6dfeb10bcdbe4aab05d630028350735556c/core/opengate_core/opengate_lib/GateSingleParticleSourcePencilBeam.h#L51

2. Leaking memory. G4AffineTransform is allocated on the heap and never freed https://github.com/OpenGATE/opengate/blob/fcaae6dfeb10bcdbe4aab05d630028350735556c/core/opengate_core/opengate_lib/GateUniqueVolumeID.cpp#L120

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. https://github.com/OpenGATE/opengate/blob/fcaae6dfeb10bcdbe4aab05d630028350735556c/core/opengate_core/g4DataSetup.py#L104

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.
