chore: do not clone for no reason in local search

refactor: pass rng as argument

Instead of having the Rng stored
inside the structs, pass it through
the functions. This means it's no longer
necessary to pass perturbations etc. as mutable.

refactor: do perturbation in place instead of cloning

chore: move env to codes/eoa_lib

tests: use random initializer in a test

feat: add new terminating conditions (or, lower than, maximum cycles)

refactor: Add dimension generic to BinaryString

chore: remove unused imports

refactor: properly handle errors in local_search

tests: Add test for sphere real representation

feat: add simple plotting of local search

refactor: abstract LocalSearch stats into LocalSearchStats

refactor: Use OVector instead of SVector in library

feat: add evolutionary strategies to local search

feat: add test for local search with PatternPerturbation

tests: add test for Linear fitness function

refactor: extend local search to accept any inputs

Instead of accepting only BinaryString, accept anything.
Extend the operators to accept anything.

tests: move all tests to separate submodules

tests: add rosenbrock test

chore: guard test imports by #[cfg(test)]
