[Scheduler] Add Scheduler.getNodeScheduling method and fix sequential function.

Feature

• Scheduling porvide a list of nodes sorted by the scheduling order

Fix

• parallel, sequential and residual function now work on python, issue with the binding and the py::explicitly_convertible function.

Refactor:

• Separate scheduling & forward in Scheduler object (linked with aidge_backend_cpu!5 (merged))
