[SRBench 2024] Requirements for the algorithms interface

[folivetti]

As we briefly discussed, for this edition we will request that the Python API of each algorithm supports:

• max_time argument that limits the runtime in seconds
• get_population() function that returns the final population (or pareto front, if MOO)
• get_best_solution() that returns the best solution as chosen by the algorithm

All of the expressions must be returned as a sympy expression.

get_population() should return 100 individuals selected by the algorithm
