Fuse bn

• Fix Add + Mul recipies
• Add fuseBN recipies
• Fix parameters issue #8 (closed)
• Update tensor to get/set values
• Add approxEq Tensor utils method to check if two tensor are approximatly equals
• Update the way scheduler is updated
• Add unit test for:
  • fuse Add + Mul
  • remove padding
  • Add unit test for fuseBN recipies (TODO in aidge_backend_cpu because of dependancie to the backend for the test)
