Inconsistency in naming conventions

[Naeemkh]

Please choose a naming convention and use it throughout the codebase, for example the following function and class names are not consistent with the code.

• _prepareRows in the following line: https://github.com/PoliUniLu/cora/blob/6efe5ca630c53f5e2bc2b9f339b5118b5a361da9/cora/prime_implicants.py#L630
• On_off_reduction_matrix in this line: https://github.com/PoliUniLu/cora/blob/6efe5ca630c53f5e2bc2b9f339b5118b5a361da9/cora/on_off_alg.py#L80
