Add flexible shop scheduling environment.

Hi @lshengjian! Do you mean the flexible flow-shop scheduling problem (FFSP) or the flexible job-shop scheduling problem (FJSP)?

If it's the former, we have supported it:

rl4co/rl4co/envs/scheduling/ffsp.py

Lines 19 to 21 in 97e90b9

 class FFSPEnv(RL4COEnvBase): 
     """Flexible Flow Shop Problem (FFSP) environment. 
     The goal is to schedule a set of jobs on a set of machines such that the makespan is minimized. 

If it's the FJSP, we don't have it in the current version. If you want, you could have a look at this tutorial to try to implement it.

Feel free to inform us if you have further questions!

I think @LTluttmann should have an implementation that is almost working, right?
