Move to package extensions

[cvigilv]

Some packages employed may not be used (CUDA, for example) based on users use case. Additionally, since Julia 1.9 we can extend the functionality of the package based on the currently loaded packages (see this link)

Tasks

• Implement CUDAExt (for GPU parallelization)
• Implement StatisticsExt (for performance assessment functions)
• Implement ROCsExt (for ROC curve performance functions)
• Add tests
• Add documentation
