add tests

[a-zakir]

The pull request introduces several changes to the project, including:

1. Updating the build scripts for various platforms (CentOS 7, Oracle 8, Ubuntu, and Windows) to use a new Cucumber test feature for Benders Outputs.

2. Modifying the C++ code for the Benders Math Logger to include delimiters in the output files. This change ensures that the data in the output files is properly formatted and easy to parse.

3. Adding new C++ tests for the Benders Math Logger to verify that the data is being written to the output files correctly.

4. Updating the Cucumber test framework to include a new feature for testing Benders criterion outputs. This feature includes steps for running the simulation, checking the simulation time, and verifying the expected positive unsupplied energy and loss of load.

5. Adding a new example test for the SmallTestFiveCandidatesWithWeights study, which includes steps for running the simulation and checking the expected overall cost, investment cost, and solution.

6. Updating the utils_functions.py file to include a new function for reading outputs from the simulation, which can handle both archived and non-archived output files.

Overall, these changes improves the testing and logging capabilities of the project, as well as adding new functionality for handling Benders criterion outputs.
